E M 319 Chapter Notes - Chapter Chapter 8: Compressive Stress

Which material is best for Pressure Vessel?

A steel cylindrical air receiver with 5 ft. diameter and pressure load of 180 psi, design stress of 9500 psi maximum. The pressure vessel is to be provided with 1 ½ in. diameter drain valve installed at the bottom of the vessel and safety pressure relief valve installed either at the top most or at the side with pop – out rating of 200 psi. Assume a 100% weld joint efficiency. The lap welding tensile strength is 65,000 psi. Determine the bursting pressure of this air receiver.

The water in a tank is pressurized by air, and the pressure is measured by a multifluid manometer as shown above. Determine the gage pressure of air in the tank.

If

=0.2 m, =0.3m, and =0.46m.

Take the densities to be:
