To eliminate dust, air with a dry bulb temperature of 38 oC and a wet bulb temperature of 27 oCscrubbed with water. The water temperature is kept at 25 degrees Celsius. The air that is expelled fromthe scrubber is in balance with water. It is then heated to 93 degrees Celsius in an air preheater beforebeing admitted to an adiabatic rotary dryer. The air exits the drier at 49 degrees Celsius. Moisture is lostat a rate of 0.05 kg of water per kg of product. The total product capacity is 1000 kg/h. Calculate thefollowing (using a psychrometric chart):isa. Total weight of dry air used per hour.b. Total volume of air leaving the dryer.

If the outside fresh-air conditions were to be 93°F dry-bulb and 74°F wet-bulb, what would the total heat content of the air be?
Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Refrigerant-134a enters the condenser of a residential heat pump at 800 kPa and 35°C at a rate of 0.018 kg/s and leaves at 800 kPa as a saturated liquid. The compressor consumes 1.24 kW of power. Use data from the tables. 800 kPa x=0 Jo Expansion valve 19H Condenser Evaporator QL Compressor 800 kPa 35°C Determine the rate of heat absorption from the outside air. The rate of heat absorbed from the outside air is W₁ kW.
An ammonia system with a 158-kW evaporator operating at -1°C and a 35-kW evaporator operatingat -40°C uses flash gas removal and intercooling. The condensing temperature is 32°C. Thearrangement is as shown. How many kilograms per minute of ammonia are compressed by the high-pressure compressor?
Steam CERE KJ -Valve Control volume boundary Turbine Initially evacuated tank In case of emergencies, a turbine is connected to an active steam pipe line using a valve. When the valve is opened, steam from the pipe line, which is initially at 550°C and 10 MPa, flows through the turbine into a 0.64 m³ tank, which is initially evacuated. The valve is closed when the pressure inside the tank is 1.6 MPa and the temperature in the tank is 300°C. If the entire process is completed adiabatically, what is the amount of work generated from the turbine?
A single effect evaporator is used to concentrate 10 000 kg / hr of tomato juice from 5% total solids to 30% total solids. The juice enters the evaporator at 25 ° C. The evaporator is operated on Steam (80% quality) at 143.27 kPa. The vacuum in the evaporator allows the juice to boil at 80 ° C. The specific heat of the dilute material is 4.1 kJ / (kg ° C) and the concentrate product is 3.1 kJ / (kg ° C). Count it (a) Steam demand rate = Answer kg / hour. b. Steam economy when condensate temperature is released at 75 ° C. = Answer (kg of water evaporated / kg of steam)
