ME 212 Lecture Notes - Lecture 1: Pressure Vessel, Gotland Regiment, Smax

The steel water pipe has an inner diameter of 12 in and wall thickness 0.25 in. If the valve a is closed and the water pressure is 300 psi, determine the longitudinal and hoop stress developed in the wall of the pipe. 

Determine the thickness of a steel air receiver with 30 inches diameter and pressure load of 120 psi, design stress of 8000 psi.

What is the difference between the pressures inside and outside a bicycle tire called?

1. Absolute pressure

2. Atmospheric pressure

3. Gauge pressure

4. None of these
