Unformatted text preview: 4 (20 points): See system below. A large compressed tank is used to supply water to a nozzle which is positioned at z = 50 m with respect of the water level in the tank. The pressure in the tank is equal to 1 MPa (gauge). The total pipe length is 100 m. The system supplies 0.2 m3/sec of water and for the nozzle to operate properly, the pressure at the nozzle inlet must be at least 200 kPa (gauge). Find the minimum pipe diameter that is acceptable for this system. Assume that the pipe is smooth. z = 50 m P at nozzle inlet (gauge) > 200 kPa P(gauge) = 1 M...
