Data at key locations are given on the figure. the mass flow rate of the water circulating through the components is 109 kg/s. stray heat transfer and kinetic and potential energy effects can be ignored. determine the net power developed, in mw. (b) the thermal efficiency. (c) the isentropic turbine efficiency. (dthe isentropic pump efficiency. (e) the mass flow rate of the cooling water, in kg/s. (f) the rates of entropy production, each in kw/k, for the turbine, condenser, and pump.

Ahypothesis is? close agreement by competent observers of observations of the same phenomena. a guess that has been tested over and over again and always found to be true. an educated guess that has yet to be proven by experiment. the long side of a right triangle. a synthesis of a large collection of information that includes guesses.

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)
