The following figure shows a supersonic engine inlet design. That engine inlet is being operated at off-design conditions with an inflow Mach number and pressure and temperature of 2.8 and 24 kPa and 200 K, respectively. The lower wall of the inlet turns through an angle of 6° towards the flow while the angle of the upper ramp is 11° towards to the flow.

Determine the flow direction and pressure in region 4 and 4’.
c) Estimate the velocity difference across the slip layer formed between regions 4 and 4’.

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

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
