A pump operating under the conditions stated in Problem 12.16 has a maximum efficiency of 0.70. If the same pump is now required to deliver water at a head of 30.5 m at maximum efficiency, determine the rotational speed, the discharge, and the required power.
Problem 12.16
A pump is designed to operate under optimum conditions at 600 rpm when delivering water at 22.7 m3 /min against a head of 19.5 m. What type of pump is recommended?
A hypersonic gun tunnel is used to generate short-duration, high-speed flows and typically consists of two cylindrical volumes separated by a diaphragm. One end of the tunnel (the driver end) is pumped to a high pressure, while the other end (the dri..
