(6) 41.3g of water is contained in an 80 liter container. When the temperature is 150 ℃, find the pressure (MPa). Show P-v diagram or T-v diagram and indicate the corresponding state

(answer number 4-8 & main question) Two vessels of different shape and sizes are connected by means of a pipe with a valve. Vessel A has a diameter of 4 ft and the length is 1.8 m at the given pressure gauge of 1476.4 in Hg and temperature of 82°F. Another vessel spherical in shape contains the same gas at 15,000 torr gauge and 18°C. The valve is opened and when the properties have been determined, it is found out that the gauge pressure is 35.7 kgf/cm2 and the temperature is 21°C. If the barometric pressure is 755 mm Hg, find the following: Volume of Vessel A in in3 - done  Pressure at Vessel A in psia - done Temperature at Vessel A in °R - done Pressure at Vessel B in psia Temperature at Vessel B in °R Pressure of the gas when mixed in psia Temperature of the gas when mixed in °R Atmospheric pressure in psi Main Question: What is the diameter of the spherical tank in inches if the gas is carbon dioxide?
