Water flows under a sluice gate on a horizontal bed at the inlet to a flame. upstream from the gate, the water depth is 1.5 feet and the speed is negligible. at the vena contracta downstream from the gate, the flow streamlines are straight and the depth is 2 inches. determine the flow speed downstream from the gate and the the discharge in ft^3/s per foot of width. how deep is the water to produce two times of the speed obtained?

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
