Consider a triplex pump having 6-in. liners and 11-in. strokes operating at 120 cycles/min and a discharge pressure of 3000 psig. a) compute the pump factor in units of gal/cycle at 100% volumetric efficiency. b) compute the flow rate in gal/min. c) compute the energy expended by each piston during each cycle and the pump power developed.

From center station, a train departs every 30 minutes on the fast line and a train departs every 50 minutes on the state line. if two trains depart from center station at 8: 00 a.m., one on each of the two lines, what is the next time that two trains, one on each line, will depart at the same time?

Individuals who live below the poverty line get seriously ill more often than those who do not what could be the hidden variable in this situation?

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
