Find the specific volume (m3/kg) for water at 500 kPa, 300 °C

A pipa transports gas up a hill. At the bottom of the hill, the maan valocity in the pipe is 10 m/sand the pressure is 200 Pa. The pipe lis then rals 10 m to the top of the hill, where the pressure is now measurad to be 30 Pa. Find the valocity at the top of the hiIL The density of the gas is 1.1 kg/m, and the acceleration dua to gravity is 3.81 m/s". P2 = 50 Pa U2 = ??? P, = 200 Pa Ah =10 m U1 = 10 m/s O. 9.53 m/s O b. 19.07 m/s O. 4.84 m/s O d. 13.29 m/s 177 m/s

A 5-kg piston in a cylinder with a diameter of 100 mm is loaded with a linear spring and the outside atmospheric pressure is 100 kPa, as shown in Figure 2. The spring exerts no force on the piston when it is at the bottom of the cylinder, and for the state shown, the pressure is 400 kPa with volume 0.4 L. The valve is opened to let some air in, causing the piston to rise 2cm. Find the new pressure.

A container is filled with 0.03 kg of Refrigerant R-134a at a temperature of 40 °C. What is the pressure if the volume is:a. 370 cm3b. 2260 cm3c. If any of the above conditions correspond to both liquid and vapor being present, find the quality of the mixture.
