measured in amps, represents how fast the energy moves through a circuit. For example, you might use horsepower and voltage to find the current in a motor. In order to calculate the current from the horsepower and voltage, you must also know the efficiency of the circuit...
A supercharger is attached directly to the engine to spin the compressor. Since the turbocharger is reusing hot exhaust to spin the turbine and compress the air, it increases the power from smaller engines. So a fuel-sipping four-cylinder can see horsepower that you might expect a six-...
If you get the power of a system in HP and the current in amps, you can calculate the volts; if you know the power and the number of volts, you can determine the current in amps; and if you have amps and volts, you can convert to horsepower. Assume you are working with a 30-HP...
First, 1 horsepower is defined as 550 foot-pounds per second (readHow Horsepower Worksto find out how they got that number). The units of torque are pound-feet. So to get from torque to horsepower, you need the "per second" term. You get that by multiplying the torque by the e...
The motor is the heart of the router. In trim routers, the motors are usually less powerful than those in larger routers but are adequate for precision tasks. The power is usually measured in horsepower (HP) or amps. Collet The collet is a sleeve that holds the router bit in place. It...
How do you convert calories to Joules using a formula? A DC motor consumes 36 MJ of energy when connected to 230 V FOR 2.5 hours. a. Calculate how many kWh is the amount of energy mentioned above. b. The power taken by the motor from the mains. c. The current taken by the motor...
Power means rate of work done.Even the unit watt is equal with joules/s. Here the hair dryer is rated 800 W means it required 800 J energy every second. Therefore we will calculate how much energy required in 3 min. The formula is {eq}\boxed{E=Pt} {/eq}....
A recommended rule of thumb is to calculate your total need, add in the overhead so your load is 75% of the rating, and then double that. That means that instead of a 9,000 watt we would buy an 18,000 watt generator to allow for future energy needs. ...
To calculate your power needs, you need to add up the normal and surge wattage figures for all of the devices you want to operate simultaneously. Here are two examples: If you plan to operate a small TV and two 60-watt light bulbs, then you need an emergency power supply that has a ...
Steam is a powerful gas and an effective heating element. To be sure, steam-turned turbines produce approximately 86 percent of electric power in the United States. From turning turbines to heating radiators, for as useful as steam can be it is still a
