A cylindrical vessel has an outside diameter of 400m and an inside diameter of 300mm for an internal pressure of 20MPa. Calculate the hoop stress at the inner and outer surfaces and at point within the wall at interval of 10mm.​

On a average work day more than work place firs are reorted

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
