The bronze C86100 pipe has an inner radius of 0.5 in. and a wall thickness of 0.2 in. If the gas flowing through it changes the temperature of the pipe uniformly from T_{A} = 200 deg * F at A to T_{B} = 60 deg * F at B, determine the axial force it exerts on the walls. The pipe was fitted between the walls when T = 60 deg * F .
