WebUseful work done formula The Useful work output of machine formula is defined as the product of load and displacement due to load and is represented as WD = W*Dl or Work … WebWork W = force * displacement Power P = W/T Where, W is the work done T is the time P is the power Example Question: An electric machine makes use of 500 J of energy to do work in 25 sec. How much does it use? Solution: Given that Work done W = 500 J Time T = 25 sec The power formula is Power = Work/Time P = 500/25 = 20

Web29 aug. 2024 · High temperature, T H = 100 0 C = 100+ 273 = 373K. Low temperature, T L = 30 0 C, = 30 +273 = 303K. Amount of the gas, n = 5 moles. Useful work done per cycle, W = Q H - Q L . Now, W = 420 J . So, Q H – QL = 420J → 1) . When the gas is carried through Carnot cycle, the heat absorbed Q H during isothermal expansion is equal to the work … WebHow do you calculate work? The formula for calculating work is Work = Force x Distance . Hence, to calculate the distance from force and work, proceed as follows: Determine the work done, W , when the force, F , is applied. Divide the work done, W … solitek solid bifacial 360 w

WebThe project has currently amassed 500 labour hours at a contracted labour cost of $50 per hour. This gives us a total labour cost of $25,000. On top of that, the project manager … WebThese quantities express the heat energy of the fuel in heat and work units, respectively. The ratio of useful work done by an engine to the heat energy of the fuel it uses, expressed in work or heat units, is called the thermal efficiency of the engine. WebHow do you calculate useful work done? You can calculate the energy transferred, or work done, by multiplying the force by the distance moved in the direction of the force. How do you calculate useful output? Hence or otherwise, calculate the efficiency of the motor. small batch yeast bread recipe
