The air conditioning process in the humidifier, air at a dry bulb temperature of 30 °C and RH of 15% increases the RH to 50%. Determine the amount of steam in the humidifier per kg of dry air. = water added (kg water / kg air).
A feed solution of 10,000 lb at 130 °F containing 47.0 lb FeSO4 per 100 lb total water is cooled to 80 °F, where FeSO4·7H2O crystals are removed. The solubility of the salt is 30.5 lb FeSO4 per 100 lb total water. The average heat capacity of the feed solution is 0.70 Btu/lb-°F. The heat of solution at 18 °C is -4.4 kcal/gmol FeSO4·7H2O. Calculate the yield of crystals and the total heat to be removed from the system.
A fully charged battery contains 0.02 kmol Ag₂O (silver oxide) and 0.02 kmol Zn (zinc). The battery is initially at a temperature of 21°C. The fully charged battery is then discharged for half an hour under adiabatic conditions (no heat leaves the system). During the half hour of being discharged, the electric current from the battery does 200 kJ of work external to the battery system (none of this external work heats the battery). During this half hour, 0.001 kmol of both reactants are consumed in the net cell discharge reaction: Please see the following table for heat capacities and heats of formation. The heats of formation below show the amount of energy (kJ) needed to form one kmole of each component. If the heat of formation is negative, then forming that species releases energy (to do work or provide heat). Therefore, to create one kmole of silver oxide 29000 kJ energy is released and is generated in the battery (for work or heat), and if one kmole of silver oxide decomposes…

A countercurrent tunnel dryer is used to dry apple slices from an initial moisture content of 65% to 5% (wet basis). Hot air enters at 95 ° C with 1% RH, and exits at 52.0 ° C. If the product temperature along the dryer is 20 ° C and the solid specific heat of the product is 2.2 kJ / (kg ° C), determine the rate of hot air required to dry the wet product at a rate of 200 kg / hr. Determine the RH of the dryer exhaust air. a. Drying air rate (ma) = kg / hr. b. RH of dryer exhaust air =%
Q1. A blackened plate is exposed to the sun so that a constant heat flux of 600 W/m² is absorbed. The back side of the plate is insulated so that all the energy absorbed is dissipated to an air stream that blows across the plate at conditions of 20°C, I atm, and 4 m/s. The plate is 30 cm square. Estimate the average temperature of the plate. What is the plate temperature at the trailing edge?
