Two spherical vessels of different sizes contain the same gas and are connected by means of a pipe with a valve. Sphere A has a diameter of 5 foot at the given pressure gauge of 50 kgf/cm2. Sphere B contains the same gas at 20 kgf/cm² gauge. The valve is opened and when the properties have been determined, it is found out that the gauge pressure is 36 kgf/cm2. The temperature at the two vessels before and after opening the valve is maintained at 21.1°C. If the barometric pressure is 750 torr and the gas inside the sphere is oxygen, find the following: The volume of sphere A is 113097.33 in3 The pressure of sphere A is 711.43 psia The temperature of sphere A is 529.98 R The pressure at sphere B in psia Temperature at sphere B in F The pressure of the gas when mixed in psia The temperature of the gas when mixed in K The atmospheric pressure in psi The diameter of Sphere B The total mass of the gas after opening the valve
