The air has a dry ball temperature of 40 ℃ and a wet bulb temperature of 26 ℃ initially heated in the heater so that the dry ball temperature increases to 90 ℃. then the air is passed through the pile of corn kernels to dry. Then this air is passed to the dehumidifier to reduce the RH to 10 ℃. Draw the course of the air change process on a psychometric diagram. The airflow rate through the corn kernels pile and dehumidifier was 6.0 m / s and the pile cross-sectional diameter was 0.5 m a. Determine the amount of water lost from the pile of corn kernels (in grams of water / second) = b. Determine the amount of water lost from the air when passing through the dehumidifier (in grams of water / second) =
Calculate 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.

THERMOFLUID A student living in a 3-m X 4-m X 4-m dormitory room turns on her 100-W fan before she leaves the room on a summer day, hoping that the room will be cooler when she comes back in the evening. Assuming all the doors and heat trans windows are tightly closed and disregarding any heat fer let through the walls and the windows, determine the temperature in the room when she comes back 8 h later. Use specific heat values at room temperature, and assume room to be at 100 kPa and 20°C in the morning she leaves.
A throttling calorimeter is used was used to determine the quality of steam supply. It was found that the pressure before and after the throttle were 1.1MPA and 0.11MPA respectively.
