Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

Why is information regarding the specific volume of gases important to the designer of air-conditioning, heating, and refrigeration equipment?
(note: multiple sub-item questions, will post in different parts.) part 1/3 A dryer is to deliver 200 kg/hr of dry product with 10 % moisture from a 275 kg/hr feed. Moist air at 25C and 18C WB is a mixture of outside air at 21C and recirculated air from the dryer, is then heated to 80C, it passed through an adiabatic dryer and leaves at 55C and 90% RH. Atmospheric air is 101 kPa. Calculate the following: 1. The moisture content of the wet product, % 2. The amount of moisture removed in the product. (kg/hr) 3. The amount of air supplied in the dryer, kg/hr
Air enters a coil in the air-handling unit (AHU) at dry-bulb temperature (Id) of 40 oC, and wet- bulb temperature (Tw) of 26 oC. The air leaves the coil at dry-bulb temperature (Td) of 12 oC, and relative humidity of 80%. This process is: Note: You need to use the psychrometric chart. O Cooling and humidification, and the air looses 50 kJ/kg of energy. O Heating and humidification and the air gains 110 kl/kg of energy. O Evaporative cooling and the air neither looses nor gains energy. O Cooling and dehumidification and the air looses 50 kl/kg of energy.
Exercise 17.5 Air is being drawn over the cold surface of the cooling coil of an air conditioning unit. If 10 m/min enters the air conditioner, calculate the mass flow rate of the condensed moisture, given that the air enters at 20°C and 70% relative humid- ity and exits at 12°C dry bulb temperature and 90% relative humidity. Calcu- late the refrigeration capacity of the coil in W and Btu/h. Solution Step 1 Draw the process diagram: ma ma W; H. H
