Assume the internal pressure varies cyclically in the cylinder from pmin=0 to Pmax , where Pmax is 60% of the estimated maximum pressure that will lead to failure by yielding as predicted by Tresca criterion. The Paris law for the material is da = 1.6 X 10 "(AK) 9 m/cycle CA a. Find the number of cycles for the crack of initial length 200 = 0.01 m to grow to a length 20 = 0.025 m. b. Find the number of cycles before the crack reaches critical length (i. e life of the part).

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
