Answer #1

$\rho 1A1V1 = \rho 2A2V2$

m1 = m2

Assuming under these conditions that air behaves as ideal gas, from ideal gas equation

$\rho 2/\rho 1 = p2T1/p1T2$

V1 = P2T1V2 / P1T2 = 18.4 * 813 *1000 / (100 * 726) = 206.049 ft/s

7. Air [R=1715 ft·lb/(slug R), cp = 6003 ft-lb/(slug-R)] flows steadily, as shown in the figure, through a turbine which produces 700 hp. For the inlet and exit conditions shown, estimate (a) the exit velocity V2 and (b) the heat transferred in Btu per hour. Hint: The specific enthalpy of an ideal gas is h = CAT. w,700 hp Turbomachine D = 6 in P = 150 lb/in? Ti - 300°F V = 100 ft/s D -6 in P2 -...
