(a) Determine the specific volume of nitrogen gas at 8.5 MPa and 139 K based on the generalized compressibility chart (Fig. A-15) and compare this result with the experimental value of 0.002002 m3/kg to (b) determine the error involved. (R = 0.2968 kPa. m3/kg. K, Tcr=126.2 K, Pcr=3.39 MPa)v

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.
