Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.

Question

An air compressor increases the pressure (P_out > P_in) and the density (?_out > ?_in) of the air passing through it. For the case in which the outlet and inlet diameters are equal (D_out = D_in), how does average air speed change across the compressor? In particular, is Vout less than, equal to, or greater than Vin? Explain.

Hello mr need sol
An air conditioning plant supplies air to a room at a rate of 1.26 kg/s, the supply air being made up of equal parts by weight of outdoor and recirculated air. The mixed air passes through a cooler coil fitted with a by-pass duct, face-and-by-pass dampers being used for humidity control. The air then passes through an after-heater and supply fan. In a test on the plant, the following conditions were measured: a. Make neat sketches showing the plant arrangement and the psychrometric cycle and identify corresponding points on both diagrams. b. Show on the plant arrangement diagram the controls required to maintain the desired room condition. c. Ignoring any temperature rise through the supply fan calculate the mass flowrate of air through the cooler coil, and the cooler coil and heater battery loads, in kW.
