An ideal reheat rankine cycle with water as the working fluid operates the inlet of the high-pressure turbine at 8000 kpa and 450°c, the inlet of the low-pressure turbine at 500 kpa and 500°c, and the condenser at 10 kpa. determine the mass flow rate through the boiler needed for this system to produce a net 5000 kw of power and the thermal efficiency of the cycle.

The metric unit of electrical power is the watt volt ampere ohm

What is the mass of the same rock on the earth

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
