A 20 ft3 container has two partitions. Partition A, whose volume is 11 ft3, contains six Ibm of air at 85 °F. Partition B, on the other part, is evacuated. The air expands freely to fill the entire container, and comes to rest with temperature of 90 °F. At this final state, a pressure gauge connected to the vessel reads 25 psi, and the atmospheric pressure is 14.7 psi. What was the initial pressure in kPa?

(D1) The client is considering the use of a manometer to measure the differential pressurebetween Tank A and Tank B for operational purposes.a) Given:s.g of A = 1.3s.g of B = 1.7s.g of manometric fluid = 1.9h1 = 1.45m, h2 = 0.75m and h = 0.4mExplain how the manometer depicted can be used to find the differential pressure between Tanks A andB. Additionally give two (2) limitations of using a manometer to measure pressure.
You and Madeline are in an aircraft flying steadily at 4,300m above sea level and you are about to experience your first sky dive with her. You jumped first but Madeline, due to hesitation, jumped after few seconds. Supposed that in an instant, the barometric pressure at your elevation is 85.0 kPa and Madeline is higher from you by 800m. Determine the barometric pressure at Madeline's elevation assuming that pressure and temperature at sea level are 101.3 kPa and 25 deg.C respectively. Use lapse rate = 0.00650 K/m
