a) Calculate the absolute pressure at a depth of 56 ft. in a lake. The atmospheric pressure is 14.7 psi.
b)If the atmospheric pressure is 100 kPa, what is the corresponding column height of a barometer using oil (SG=0.91) as its working fluid.
c)A vacuum gage connected to a container reads 65 kPa. If the atmospheric pressure is 101 kPa, what is the absolute pressure inside the container?
