A pump with an efficiency of 15mm% is used to pump water from a tank (stationary water inside) at the ground to an open swimming pool (atmospheric pressure) at the top of a residence, where surface of the swimming pool has an elevation of 35m. The pressure in the tank in the ground is measured to be 150 kPa absolute. The electric consumption of the pump is measured to be 1kW. What is the mass flow rate of the pump? Write the general first law of thermodynamics for an open system between two points, reduce it to steadystate mechanical energy equation for incompressible flows (like water). Take atmospheric pressure to be 100 kPa absolute
