Question

1. A storage tank of negligible mass and 30m high is filled with gasoline. Please calculate the following: (a) The gauge pressure and absolute pressure at the bottom of the tank. 4 pts (b) The force that acts on a square access hatch at the bottom of the tank that measures 0.5m x 0.5m. 2 pts (c) Given that the tank is shaped like a right circular cylinder with a height of 30 m and with a base radius of 10m. The tank is attached to a steel cable of negligible mass and immersed in water. Calculate the tension (force) in the cable before and after it is immersed in water.

Explanation / Answer

Pressure = density x mgh Pg = 0.680 x 1000 x 9.8 x 30 Pg = 1999200Pa
