1. The problem statement, all variables and given/known data Steam at 200psia and 600 *F [state 1] Enters a turbine through a 3-inch-diameter pipe with a velocity of 10(ft)/(s). The exhaust from the turbine is carried through a 10-inch-diameter pipe and is at 5psia and 200 *F [state 2]. What is the power output of the turbine? H1 = 1,322.6(Btu)/lbm H2 = 1148.6(Btu)/lbm V1 = 3.058ft^3 / lbm V2 = 78.14ft^3 / lbm 2. Relevant equations dH = (u^2 / 2*gc) + Q + W 3. The attempt at a solution dH = -174Btu/lbm 174Btu/lbm = du/2gc + Q + W mass flowrate = (A1*u1) / V1 == 0.1605 lbm/s final velocity u2 = (m * V2) / A2 = 23.0 ft/s du = 13ft/s What do I do now? How do I calculate Q and W? there are tables at the back of the book with properties of steam for various temperatures and pressures...some of the example problems I looked at make use of that, but I'm not quite sure how that helps here.
