In rural housing, the source of water is obtained through groundwater pumped up. Assume that the groundwater source is 60 m deep from the surface. Water will be lifted as far as 5 m above ground level by pump. The inlet diameter of the pipe is 10 cm and the outlet is 15 cm. Ignoring the interaction of heat with the environment and heat due to friction, determine the input work (Watts) required by the pump so that the water flows steadily at a rate of 15 liters/s. (The density of water is 1000 kg/m^3).
