An electric motor is used to pump water out of a well that is 12m deep. In one minute, 200kg of water is pumped up from the well. What is the power consumption of the electric motor if it is working at 80% efficiency?

The four giant gas points that are made primarily of lightweight elements are

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines.
