For water with pressure of P=8MPa and specific volume v=0.023525 m3/kg,   (2) Find the specific volume of the saturated liquid vf___________m3/kg

Using the tables for water, determine the specified property data at the indicated states. (a) At p = 3 bar, v = 0.3 m³ /kg, find T in °C and u in kJ/kg. T = U = (b) At T = 320°C, v = p = U = V = h = °C P = kJ/kg = 0.034 m³ /kg, find p in MPa and u in kJ/kg. (c) At p = 28 MPa, T = 400 °C, find v in m³ /kg and h in kJ/kg. m³/kg h = MPa kJ/kg (d) At T = 10°C, v = 100 m³ /kg, find p in kPa and h in kJ/kg. kJ/kg kPa kJ/kg

A piston/cylinder apparatus initially contains 0.4 kg of saturated water vapor at a pressure of 200 kPa. The water vapor is now heated until the (extensive) volume of the H,0 is 0.5 m³ (state 2). (a) Fill in the following table. H,0 State Temp. T(C) P (kPa) Specific volume Volume Specific internal energy u (kJ/kg) 2529.1 Pressure P, = 200 kPa V (m?) Sat. vapor v (m³/kg) 1 200 0.5 state 1. (b) Determine the total work done by the H20 during the process, 1→2. (c) Determine the total heat transfer to the H,0 during the process, 1→2. (d) Draw the process on a P-v diagram. Label both states. (e) EXTRA CREDIT: Determine the change in enthalpy of the H20 from 1>2 and explain why this answer makes sense.

A typical gasoline (β=0.00095/°C)  tank can hold 65 liters (~17 gallons). At the gas station, the storage tank is underground and is maintained at a temperature of 50.0°F. On a hot day at 103.0°F you fill your empty tank. (a) What is the equivalent temperature difference in °C? A typical gasoline (β=0.00095/°C)  tank can hold 65 liters (~17 gallons). At the gas station, the storage tank is underground and is maintained at a temperature of 50.0°F. On a hot day at 103.0°F you fill your empty tank. (c) How much gas should you put in your car on this hot day at so that it will fill (not overfill) the tank when it expands to 103.0°F?
