For any engine you can calculate the amount of fuel used, its thermal efficiency and its horsepower potential. For reasons of simplicity let’s take an engine that makes HP. It may use approx 24 gallon per hour to make HP. 1 Gallon of fuel weighs approx lbs and for every 1 lb of fuel burned app BTU’s of energy is released.

horsepower was first developed to unify a measure of work output. thrust, as justin stated, is a force which is not work. im sure there is something out there that can give you somewhat of a ballpark but that would mean me calling my mom to have her mail me out my old ap physics book. Definition. The kilowatt-hour is a composite unit of energy equal to one kilowatt (kW) of power sustained for one hour. Expressed in the standard unit of energy in the International System of Units (SI), the joule (symbol J), it is equal to kilojoules ( MJ).. The hour is a unit of time listed among the non-SI units accepted by the International Bureau of Weights and Measures for use SI units: MJ.

In other words, volt-amps x power factor = watts. Similarly, KVA*PF = KW, Or kilovolt-amps times power factor equals kilowatts. When you want to know how much the electricity is costing you, you use watts. When you are specifying equipment loads, fuses, and wiring sizes . There are watts in one horsepower, so every time a motor develops or uses watts it has done one horsepower of work. Both wattage and horsepower are two ways of stating the same thing. This is why the watts per horsepower is divided into the watts on the top of the formula.

Before Knowing anything else, first we need to know what is power. Power is the rate of work done or work done per unit time or energy converted per unit time. Now though the basic concept remains the same, the expressions of power differs in elec. 1kW = hp. Technically, this form of measurement is the most uniform method of measuring power and is used by every engineer worldwide.

Watts are an SI unit (International System) which means. Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors.

There are many different standards and types of horsepower. Two common definitions being used today are the mechanical horsepower (or imperial horsepower), which is about watts, and the metric horsepower, which is approximately.

There's no sensible answer to that. CC is volume, cubic centimeters, the contents of a tiny box one cm wide, high and tall. One kilowatt is a measure of power, about one-and-a-third horsepower.

Kilowatts (kW) and horsepower (hp) are both measures of power, and converting one to the other is a matter of multiplying by a conversion factor. One horsepower is equal to kW, and one kilowatt equals hp. Neither unit is a reliable measure of an air conditioner's cooling power, though, because neither takes into account the.

Wholesale electrical supplies. An electrical distributor supplying everything from light bulbs and dimmers to PLCs and Industrial Automation equipment. Hundreds of electrical products and tools to select from. Use the chart in this calculation guide to find the formula.

A kilowatt-hour is the amount of energy equivalent to a power of 1 kilowatt running for 1 hour. If you leave a Watt light bulb on for 1 hour, you’ve done gone and used up watt-hours. But your electric company will bill you by the kilowatt-hour, so you’ll get a.

Shaft h-p (horsepower) is the power output of an engine. Brake h-p is the power available at the wheels of a vehicle - or at whatever other type of load the engine is set-up to drive. Numbers play a large part in the HVAC industry.

The numbers involved are more complex than, the difference between 35 and 95 degrees. A good quality HVAC engineer needs to be familiar with complex numbers and calculations. As with any mathematical solution, it is easy when you know how. A Complete Guide To HVAC Formulas [ ].

kw to hp hp = watts / Electrical formulas - electrical calculation - power calculation- horse power - kilowatts to horse power - how to calculate hp. kW stands for kilowatt. A kilowatt is simply 1, watts, which is a measure of power.

So, for example, watt electric shower in the top bullet point above could also be called a 10 kilowatt shower. A kilowatt hour (kWh) is a measure of energy.

So a 1, watt drill needs 1, watts (1 kW) of power to make it work, and uses 1 kWh of. Basically, Power is defined as work done per unit time. And the unit of Work/Energy is Joules.

So as per the definition, unit of power is Joules per Second, which is termed as Watt after the physicist James Watt. This unit can be altered as kilow. Liquids can have the power of horses. Hydraulic horsepower refers to the power that a hydraulic system can generate.

The horsepower depends on the gallons per minute (gpm) of the flow of fuel and the pressure rate of pounds per square inch (psi). If you know. kilowatt – kW horsepower – hp kilowatt hour – kW-h British thermal units per hour – Btu kilowatt hours – kW-h Kilojoule – kJ 3 meter – m feet – ft Newton – N pound force – lbf 8 SI Prefixes Power of Ten Name Symbol tera T giga G File Size: KB.

Thus, it is found that 5 kilometers per second is equal to meters per second. Software tools. There are many conversion tools. They are found in the function libraries of applications such as spreadsheets databases, in calculators, and in macro packages and plugins for many other applications such as the mathematical, scientific and technical applications.

To calculate torque, you will need to have calculated the power of the vehicle and RPM. If you do not have the RPM figure, it can be generated in VBOX Test Suite or VBOX Tools using Maths Channels, as detailed below.

To calculate Torque in Nm, create a new Maths Channel and enter the following equation: Power (kW) * / rotational speed (rpm). Influence of compression ratio on the performance characteristics of a spark ignition engine Aina T., Folayan C.

and Pam G. is the total fuel consumed per kilowatt power developed and it is given by [4] an equation for the relation between the engine torque and Cited by: 9.

that is used in the CAFE standard to calculate the fleet average fuel economy (the sales weighted average) for the city and highway cycles. The details of this calculation are shown in Appendix consumption is also the appropriate metric for determining the yearly fuel savings if one goes from a vehicle with a given fuel consumption to one with a lower fuel consumption.

Need to Find: Formula: Horsepower DC (Volts x Amps x Efficiency)/ Horsepower AC (Volts x Amps x x Eff x PF)/ Blue = Horsepower Red = Torque Green = Motor Nameplate Frequency (60 Hz) In Constant Torque Area - VFD supplies rated motor nameplate voltage and motor develops full horsepower at 60 hertz base frequency.

In Constant Horsepower Area - VFD delivers motor nameplate rated voltage from 60 Hertz to hertz (or drive maximum). Motor horse-File Size: KB. Since the calculated value ( Amp) at 40°C (°F) is less than that of current carrying capacity of (7/) cable which is 28A, therefore this size of cable (7/) is also suitable with respect to temperature.

Now find the voltage drop for feet for this (7/) cable from Table 4 which is 7V, But in our case, the length of. A Newton is a force, a Watt or a horsepower is a power. A power is a force * distance / time, or a work / unit time. Something that moves 1 Newton, 1 metre in 1 second will do 1 Watt of work, if it is perfectly isentropically efficient.

What you're probably talking about is power-producing engines vs. thrust-producing engines.One horsepower, abbreviated as “HP”, equals the work required to l pounds one foot (33, foot-pounds) in one minute.

This is the same as lifting pounds one foot in one second. Often it is necessary to convert power from one unit to the other, and the equation in figure 2 is used to change horsepower to watts or watts to.
