U-tube manometer are commonly used to measure pressure Po of the air space inside a water tank, see figure below. Given readings (measure from ground level) 20 = 200 cm, 21 = 90 cm, z2 = 120 cm, zz = 100 cm 24 = 110 cm. Determine the gauge pressure Po - Pa.

A constant pressure piston/cylinder has 1 kg of saturated liquid water at 100 kPa. a rigid tank contains air at 1200k, 1000 kPa. they are now thermally connected by a reversible heat engine cooling air tank and boiling the water to saturated vapor. Find the required amount of air and the work out of the heat engine.

Air 250 kPa Problem6 A tall tank has an orifice (circular opening) located 2.5 m below the water surface. The tank is closed with an ABSOLUTE pressure of 250 kPa. Atmospheric pressure is 100 kPa. (a) Neglecting frictional effects, determine the flowrate out of the tank. (b) As the tank empties, will the flowrate increase, decrease, or remain the same? Prove your answer with equations and words. Assume the air pressure in the tank remains constant. 2.5 m 10 cm
QUESTIONS 1. Refrigerant-134a is cooled by water in a condenser. The refrigerant enters the condenser at a pressure of 1 MPa and a temperature of 70°C at a flow rate of 6 kg / min and exits at a temperature of 35 °C. Cooling water enters the condenser at 300 kPa pressure and 15 °C temperature and exits at 25 °C temperature. By neglecting pressure losses, Calculate; a) mass flow of cooling water b) the heat transfer from the refrigerant...
