Consider a frictionless fluid with a density of 65 lbm/ft3. We describe this fluid as:
phi19= (-11 1/s)*(x^2-y^2)
The pressure at x = 0, y = 0 is 22 psia. Calculate the pressure at (x, y) = (0.75 ft, 0.75 ft) and at (x, y) = (4 ft, 0 ft).
Steam enters an adiabatic nozzle steadily, at 2.5 Mpa and 400°C with a velocity of 50 m/s and exits at 1 MPa and 380 m/s. If the nozzle has an inlet area of 65 cm2, determine: The exit temperature. The rate of entropy generation for this process, in..
