QUESTION 2 A new induced raft cooling tower is circulating 120 000 L/h of water that is cooled from 50 °C to 22 °C. How much blow-down and make-up is required to maintain the concentration of dissolved solids in the circulating water at four times the concentration in the make-up water? Assume the following: - The evaporated water contains no dissolved solids so all solids entering the system in the make-up must be removed by blow-down and windage. - The windage value of the induced draft cooling tower is 0.3% for each 5.6 °C. - The evaporative losses value is 1.1%.

2. Two hundred and fifty pounds of a mixture of 10 mol% propane 20% n-butane, and 70% n-pentane is completely vaporized in a pipe still in one hour. At the outlet, the temperature anc 433 F and 600 psia. What is the volumetric flow pressure are rate in cfm at the outlet conditions? Answer: The physical properties of the gas are: Tc Pc MW Propane 369.9 K 665.8 R 42.0 atm 44 Butane 425.17 K 765.31 R 37.47 atm 58 Pentane 469.8 K 845.64 R 33.3 atm 72
In continental interior areas of Canada, winter air is usually cold and dry (contains little moisture vapour). Suppose the outside temperature is -10 °C and the relative humidity is 70%. If this air is then brought into a building and heated to 20 °C, what will the new relative humidity be? What kind of conditions would a person living or working in this building experience?
Using a psychrometric diagram, describe the process and humidification of the following data. Initially the air was at a dry bulb temperature (DBT) of 35 ° C and RH of 45%. The air is heated to DBT 85 ° C. The heated air is then flowed through a humidifier to increase the RH to 25%. For this process, calculate, a.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)

The air entering a continuous flow air conditioning system at 1 atmosphere pressure, 15 ̊C temperature and 80% relative humidity with 50 m3/min flow rate is first heated to 25 ̊C and then humidified by spraying steam. It exits the air conditioning system at 30 ̊C and 40% relative humidity. Using the psychrometric diagram; Calculate a) the amount of heat transferred to the air in the heating section and b) the amount of water vapor added to the air
Moist air at 21 C° DBT and 15 C° WBT and standard atmospheric pressure is humid by water spray.

Wastewater containing lead is being released from a certain industrial plant. The stream contains X.YZ % Pb and is treated in a unit (maximum capacity = 5000 kg wastewater/hr) that removes 90% of lead in the feed, which is then recycled back into the plant. Another stream from the unit is being released to a lagoon. If the stream leaving the plant has a rate greater than that of the treatment unit. the excess of the capacity of the unit (say, the excess above 5000 kg/hr) bypasses the unit. This excess is combined with the liquid leaving the treatment unit, which is released into the lagoon. The treatment plant releases 7500 kg/hr of wastewater. Let X.YZ be 7.23 Calculate the mass fraction of Pb in the waste lagoon stream. Express your answer in 4 decimal places.
Outside air at 30 C drybulb & 25 C wetbulb temperature flowing at a rate of 25,000 liters/min is mix with colder air at 20 C drybulb & 18 C wetbulb temperature flowing at a rate 70,000 liters/min. After mixing , the mxture undergoes sensible heating up to 40 C . Compute the heating needed in kW. Plot the process on the Psychrometric chart and label it completely. Can you upload the chart also?
