Question

!. An on-farm diesel fuel tank is on a stand 4 feet above the ground. The tank is vented to the atmosphere (the air in the tank is at atmospheric pressure). If the diesel level in the tank is 4 feet above the release point. If the density of diesel is 6.98 pounds/gallon, what is the gauge pressure of the fuel at the nozzle?

What is the absolute pressure?

Gauge Pressure = ________ psi

Absolute Pressure = __________ psi

2. A submarine dives to a depth of 300 feet. The interior of submarine is maintained at atmospheric pressure. What is the gauge pressure and total force applied to a hatch 2 feet by 2 feet?

(assume the density of seawater is 65 lbs/ft³)

Gauge Pressure = _________ psi

Applied Force = ___________pounds
