A spherical gas container having an outer diameter of 15 ftand a wall thickness of 0.90 in. is made of a steel for whichE =29*106 psi and v = 0.29. Knowingthat the gage pressure in the container is increased from zero to250 psi, determine
a) the max normal stress in the container,
b)the corresponding increase in the diameter of the vessel.
How to get the increase in diameter?
The mine's operating costs were projected at $900,000 per year including $400,000 of fixed costs and $500,000 of variable costs. Ms. Peru thought these forecasts accurate.
A chemical plant uses a tube-within-a-tube counterflow heat exchanger to heat air with the use of steam. During steady state operation, the air flows into the exchanger at a rate of 5,000 kg/h and a temperature of 27C and exits at a temperature..
The water level of the reservoir is 150 ft above that of the tank. The intake end of the pipeline is square-edged (k=0.5) and the water coes into the tank through a submerged end (k=1). You are told that the pipe is 12 in in diameter
