Solutions to ce 2200 homework assignment #1: problem-2. 7: natural gas is stored in a spherical tank at a temperature of 10oc. At a given initial time, the pressure in the tank is 100 kpa gage, and the atmospheric pressure is 100 kpa absolute. Sometime later, after considerably more gas is pumped into the tank, the pressure in the tank is 200 kpa gage, and the temperature is still. Step-1: problem statement: find the ratio of the masses of the natural gas at two different pressure conditions. Step-3: assumptions and approximations: temperature and volume are assumed to be constant for the initial and final conditions. We have given that the 100 kpa gage in the tank and atmospheric pressure is 100 kpa absolute. The gage pressure is the difference between atmospheric pressure and pressure in the tank. will be used for this problem. p (cid:85)(cid:32) Rt p tan1 k (cid:32) (cid:16) p p.
