WebFind the efficiency of the motor. Solution: P in = 50W. E = 2970J. t = 60s. P out = E / t = 2970J / 60s = 49.5W. η = 100% * P out / P in = 100 * 49.5W / 50W = 99%. Energy … WebThe efficiency is given as. η ={ Work Output / Work Input }× 100 % = {140 / 600} × 100 % = 23.3 %. Example 2. A heat engine gives out 500 J of heat energy as useful work. …
WebJul 23, 2024 · How to calculate efficiency ― Efficiency formula. As we said, efficiency is the ratio between energy output and energy input. We summarize this in the efficiency … WebWhat is the efficiency of a machine? The efficiency of any machine measures the degree to which friction and other factors reduce the actual work output of the machine from its theoretical maximum. A frictionless machine would have an efficiency of 100%. A machine with an efficiency of 20% has an output of only one-fifth of its theoretical output.
WebJun 13, 2024 · To calculate availability, use the formula of MTBF divided by (MTBF + MTTR). By continuing with the above example of the AHU, its availability is: 300 divided by 360. The result is 83.3 percent availability. Probability of failure. This calculation gets a little more complicated mathematically. WebPerformance is how the equipment is performing against its capacity. In this calculation, we use the ideal cycle time and operating time to determine how many parts the machine can produce under ideal operating conditions. We then calculate the ratio of how many parts we actually produced versus the capacity. Capacity Formula:
WebMar 3, 2024 · 3. Divide actual output by potential output. Once you calculate your actual output and estimate your potential output level, divide the actual output by the potential output. Using the previous examples in the formula, divide the two output values: Capacity utilization = (100,000 / 225,000) x 100 = (0.44) x 100. 4.
