Engine loses some of its generated power while overcoming its own friction known as ‘Frictional Horse Power’. ‘Indicated Horse power‘ is the actual power developed by the engine whereasBrake Horse Poweris theavailable powerwhich is almost about 70 to 85 % of theactual powerdeveloped inside t...
The equation to calculate horsepower is simple:Horsepower = Torque x RPM / 5,252. You can use our horsepower calculator below to try it out yourself. When it comes to understanding how a dynamometer measures torque and calculates power, it will help to know a few more basic definitions and ...
Bending allowance can be used to calculate the unfolded length of a flat sheet metal, which for bending to be a specific radius and angle. The calculation takes into account the thickness of the sheet metal, the bending radius, the bending angle and other material properties (such as Y and ...
Scottish Engineer James Watt invented the horsepower metric in the late 18th century to compare the output of steam engines with the power of draft horses. Watt realized that horsepower could be used to express the rate of engine power. How do you calculate horsepower? The answer is simple: h...
After all, it's more than just mashing the brake pedal. Let's take a look at each briefly. Tires and Traction Tires are one of the most important elements when stopping a vehicle quickly and efficiently. When engineers calculate braking distance, they use several variables. One of them is...
Equation 1 is only used to calculate the brake horsepower from the measured current as to compare with the nameplate data. Overestimating energy and cost savings of installing VFDs Modern thinking always brings in the 110 hp as brake horsepower, but often gets the nominal horsepower distorted by...
Power is calculated by dividing the amount of work done by the time it takes to do it. Power is often given in units of horsepower or watts, although other units such as ft-lbf/min, calories/hour and BTU/sec are also used. The unit “horsepower” is defined differently depending on wh...
Brake horsepower When you size a PD pump it will be important to select the correct brake horsepower. Brake horsepower (BHP) is the power the pump requires to overcome the discharge pressure. BHP is determined by adding the work horsepower (WHP) and the viscous (VHP) horsepower. BHP = WHP...
As expected, the higher the recuperation power, the less the battery is depleted. The braking strategy seems to have an even bigger impact on the state of charge. The following plot shows the sections on the track where the mechanical brake is being used for a recuperation power of 20 kW ...
GPS Math: Using Timing to Calculate Distance A GPS satellite Photo courtesy U.S. Army At this point, you could confidently tell someone you want to impress that GPS works via trilateration. But you should be prepared for the follow-up question: How does the GPS device know the distance...
