Determine the temperature, volume, and quality for one kg water under the following conditions: a. U = 3000 kJ/kg, P = 0.3 MPa b. U = 2900 kJ/kg, P = 1.7 MPa c. U = 2500 kJ/kg, P = 0.3 MPa dU = 350 kJ/kg, P = 0.03 MPa

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
