Required information Problem 14.095 - Evaporative Swamp Cooler NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Air enters an evaporative cooler at 1 atm, 40°C, and 20 percent relative humidity at a rate of 7 m³/min, and it leaves with a relative humidity of 90 percent. Use data from the psychrometric chart. 1 atm 40°C 20% Air Water Mw Humidifier € £2=90% Problem 14.095.a - Evaporative Swamp Cooler Determine the exit temperature of the air. The exit temperature of the air is °C.
Part b) You can use psychrometric chart to solve this part of the question. (while submitting file response answers, you may also submit picture of your working on psychrometric chart) At steady state, a cold moist air stream (stream 1) of 0.1 m/s is available at 10°C, 1 atm, and 10% relative humidity. A hot moist air stream (stream 2) at 40°C, 1 atm, and 60% relative humidity is mal W2-W3 %3D also available. It is required to mix the 2 streams adiabatically to obtain a single stream (stream 3) at a temperature of 20°C. (hint: W3-W1 maz i) Determine the humidity ratio of stream 3 kg/kg of dry air. m3/s. ii) Determine the volume flow rate required for stream 2
EXAMPLE 5 In an oil refinery, a storage tank contains 2000 gal of gasoline that ini- tially has 100 lb of an additive dissolved in it. In preparation for winter weather, gasoline containing 2 lb of additive per gallon is pumped into the tank at a rate of 40 gal/min. The well-mixed solution is pumped out at a rate of 45 gal/min. How much of the additive is in the tank 20 min after the pumping process begins (Figure 16.7)? dy dt 40 gal/min containing 2 lb/gal The differential equation modeling the mixture process is dy dt y(t)\ (40 × 2) - (45 × V(6) X = 80- 45 y(t) 2000-5t/ Apply Euler's methods to find y(20) = ?

Using a psychrometric diagram, illustrate the heating and humidifier process from the following data. Initially the air was at dry bulb temperature (DBT) 40 ˚C and RH 30%. Air is heated to DBT 90 ˚C. The heated air is then flowed through a humidifier to increase the RH to 25%. For this process, calculate, a. Change in absolute humidity of air from initial to final conditions = kg water / kg air). b. The change in air enthalpy from initial to final conditions. = (kj / kg air)
On a certain day, the temperature is 25.0ºC and the relative humidity is 90.0%. How many grams of water must condense out of each cubic meter of air if the temperature falls to 15.0ºC ? Such a drop in temperature can, thus,produce heavy dew or fog.
Given the same temperature, if we reduce the water vapor content of the air sample in the previous question to 12% relative humidity (RH), what would the dew point be?
