The tank of the air compressor is subjected to an internal pressure of 0.63 mpa. if the internal diameter of the tank is 550mm, and the wall thickness is 6mm (a). construct a net mohr's circle depicting the state of stress acting at any point along the length of the 20 marks (b). illustrate the state of stress above on a differential element (infinitesimal cube).

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

Air at a pressure of 1atm and a temperature of 40 c is in parallel flow over the top surface of a flat plate that is heated to a uniform temperature of 120 c. the plate has a length of 0.40m (in the flow direction) and a width of 0.15m. the reynolds number based on the plate length is 50, 000. what is the rate of heat transfer from the plate to the air? if the free stream velocity of the air is doubled and the pressure is increased to 10 atm what is the rate of heat transfer?
