The yield strength for an alloy that has an average grain diameter of 5.9 × 10-2 mm is 128 MPa. At a grain diameter of 6.6 × 10-3 mm, the yield strength increases to 268 MPa. At what grain diameter, in mm, will the yield strength be 236 MPa?

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

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