Estimate the convective heat-transfer coefficient on the outside of cherry (external diameter 2.4 cm) when submerged in a stream of chilled water pumped around the cherry. The surface temperature of the cherry is 25ᵒC and the bulk water temperature is 5ᵒC. Given NRe=5000.

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

Explain in your own word the concept of a solid solution, in alloys, and how it can be created.

At steady state, air enters an insulated duct of varying cross-sectional area (similar to a nozzle or diffuser) at 200 kpa, 52°c with a mass flow rate of 0.5 kg/s. at the duct exit, the pressure of the air is 100 kpa, the velocity is 255 m/s, and the cross-sectional area is 2 x 10-3 m^2. assuming an ideal gas model, determine: a)-find the specific volume of the air at the exit, in m3/kg. b)- the temperature of the air at the exit, in k. c)-the velocity of the air at the inlet, in m/s. d)-the inlet cross-sectional area, in m^2.
