The power output of an adiabatic steam turbine is 5 mw, and the inlet conditions of the steam are as p1 = 2 mpa, t1 = 400°c, v1 = 50 m/s, z1 = 10 m, and exit conditions are given as p2 = 15 kpa, x2 = 90%, v2 = 180 m/s, z 2 = 6 m. thus,
(a) compare the magnitudes of h, ke, and pe. [ dh=-887.39 kj/kg; dke=14.95 kj/kg; dpe=-0.04 kj/kg]
(b) determine the work done per unit mass of the steam flowing through the turbine.[ 872.48 kj/kg]
(c) calculate the mass flow rate of the steam.[ 5.73 kg/s

Can you match these to the correct definition

Panel bc in fig. p2.76 is semi-circular, with the 3 meter radius and horizontal straight edge through point b. compute (a) the hydrostatic force of the water on the panel, (b) its center of pressure, and (c) the moment of this force about point b. assume atmospheric pressure on the dry side of the panel

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. the athlete is able to rotate the ball at the rate of 8.13 rev/s when the length of the chain is 0.600 m. when he increases the length to 0.900 m, he is able to rotate the ball only 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2
