Two spherical shape container with diameter of 6 feæt are connected to each other by means of a short pipe with valve closed. Each container contains helium gas at 70 degrees F, one contains 4.2 pounds and the other one contain 18 pounds. If the valve is opened. calculate the resulting pressure of mixture.
