A thermodynamic steady flow system receives 11 lbm/s of a viscous fluid where P1 = 40 psi, ρ1 = 70 lbm/ft^3, V1 = 350 ft/s, and u1 = 227 lbf/lbm. The elevation of the inflow is at zero-elevation. The fluid leaves the system at 100-foot elevation at a boundary where P2 = 18 psi, ρ2 = 80 lbm/ft^3, V2 = 400 ft/s, and u2 = 150 ft-lbf/lbm. During passage through the system, the work done by the fluid is 90 ft-lbf/lbm. Determine the heat added/rejected to/by the system. Assume g = 31.20 ft/s^2.
