Design a cylindrical pressure vessel to carry compressed air for a self-contaihed breathing apparatus for use by firefighters when operating in smoke-filled buildings. The minimum inside diameter is to be 20 cm, and the length of the cylindrical portion of the tank is to be 45 cm. It must withstand a service pressure of 4.0 MPa. Use a design stress of S/8 to account for a large number of pressurization cycles. The tank is to be made from aluminum alloy 6061- T6

If the compressor suction pressure is 70 pounds per square inch gaugepressure (psig) and the outside temperature is 85°F, what should thedischarge pressure be reading?

Compare the pressure in question 1A to the pressure in 4A and explain any differences.    I got question 1A to the pressure P=145.3atm or 147.53kPa I got question 4A to the pressure 1.4357atm

10. A long, thin-walled cylindrical tank of length L just fits between two rigid end walls when there is no pressure in the tank. Derive the correct expression for the force exerted on the rigid walls by the tank when the pressure in the tank is p and the material of which the tank is made obeys Hooke's Law. Solve the result for p = 200 psi, r = 2 ", t = 1/8 ", v =0.3. L 2r t
