Assume the alternator is 8 0 % efficient (its output electrical power is 8 0 % of its input mechanical power), and calculate the horsepower the engine must supply to run the lights. Use the calculator that corresponds to your desired units of measurement. However, when determining the input power required for the motor, the efficiency of the gearmotor assembly at transmitting that power to the load must be taken into account. 19 In. Mechanical power is also described as the time derivative of work. This excel file will help you to calculate power and electricity production according to load, fuel consumption and cost of kWh . Calculation of power requirements is often used as a preliminary step in motor or gearmotor selection. as they relate to the sound changes heard from the power unit during the lab. It's measured in joules (J). The mechanical power which is the energy per unit time released to the respiratory system according to the applied tidal volume, PEEP, respiratory rate, and flow should reflect the ventilator-induced lung injury. Mechanical Power is denoted by Pm symbol. Hm = Energy or pressure loss of the hydraulic network expressed in m. The relationship between Power, rotational Speed (in RPM) and Torque is fixed.
