Fora 3000-ft3 combination and exercise operation, it is desired to reduce the outdoor air intake rate to a minimum by filtering and air recirculation. (a) Design a system using filters having an efficiency of 0.50 and a pressure loss of 0.14 in. wg at 350 ft/min face velocity. Pressure loss should not exceed 0.20 in. wg. Outdoor air contaminants are negligible. (b) Discuss how the choice of a filter would be influenced in this case should the cooling load require a larger supply air rate than the ventilation.

- I need answer within 20 minutes please please with my best wishesarrow_forward1. In less than 100 words, describe how the reciprocating air compressors (applicable to a particular purpose) can be improved in terms of sustainability in terms of energy use and pollution effect. 2. Cost implications or projections data/calculations from the idea(s)arrow_forwardCalculate the EER rating of a 20 ton (240000 Btu) air conditioning unit with an average electrical load of 30 kW. An air conditioning plant supplies air to a room at a rate of 2.5 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 (Table Qu 4) were recorded; 3 Table Qu. 4: Parameters recorded Relative humidity Dry bulb temperature °C Wet bulb temperature °C % Outdoor air 270 20.5 Room air 210 50 Supply air Air leaving cooler 160 11.8 80 90 coil Make neat sketches showing the plant arrangement and the psychrometric cycle and identify the corresponding points on both diagrams. Calculate the following; mass of air through the cooler coil load on cooler coil load on heaterarrow_forward

- A continuous flow calorimeter was used to obtain the calorific value of a sample of fuel and the following data collected: Mass of fuel: 2.25kg Inlet water temp: ll CQuantity of water: 360 L Outlet water temp: 60 CCalorimeter efficiency: 85 % Calculate the calorific value of the sample (kJ/kg).arrow_forwardWhy is compressed air supplied to the sewage treatment plant on board? What is its importance and role?arrow_forwardPls. Answer thank you! The inside design conditions for a conditioned space are 20.1°C dry-bulb and 15.2°C wet-bulb. The air temperature increases 10.6°C as it passes through the conditioned space. The apparatus dew point is 11.9°C. The heat transfer rate is 456 Kw. What is most nearly the volumetric flow rate of the air passing through the space?arrow_forward
