8. consider laminar viscous flow over a flat plate. we will earn later in the course that the skin friction coefficient cf is given by cf = 0.664 / (rex)0.5 where rex is the reynold number based on the distance from the leading edge of the flat plate x, and is defined as rex = [infinity]u[infinity]x/[infinity] . here [infinity] is freestream density, u[infinity] is the freestream velocity, and [infinity] is the molecular viscosity. a) integrate cf over the non-dimensional

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

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
