Reference no: EM13252675

Water is being pumped from a pond (elevation = 50 m) up to a pistachio farm (elevation = 150 m). The diameter of the tubing throughout the system is 10 cm and the average velocity of water in the tube is 5 m/s. The friction loss in the entire piping system (excluding the pump) is 20 J/kg. If the pump is 50% efficient, how much energy (in J/kg) must the pump supply? (Report answer in units of J/kg).
