A large tank filled with water and open to the atmosphere is used to extinguish a fire in an ethylene production plant. The water is removed from the tank through a pump and then distributed to the hoses. It is desirable to deliver 1890 L of water per minute at a pressure of 15 bar. If the pump has an efficiency of 70.0%, how much labor must be supplied to the pump to meet discharge specifications?
