Assignment Help:

Steam flowing at a rate of 3200 lbm/hr enters an adiabatic nozzle. The initial condition of steam is: P1 = 250 psi, v1=620 ft/min, v1 = 2.4 ft3/lbm and u1 = 1125.5 Btu/lbm. The steam exits at: P2 = 35 psi, v2 = 18.5 ft3/lbm and u2 = 985 Btu/lbm. Determine the exit velocity of the steam in ft/sec.
