Air flows through a 3 m long, 15 cm x 2 cm duct at 2 m s^-1. if the duct surface is held constant at 25°c and the inlet air temperature is 75°c, use an appropriate correlation to calculate the outlet temperature of the water and the rate of heat transfer.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)
