this is a chemical process principles question. energy balance. pls provide full ans with legible handwriting. thanks.

Air could be humidified or dehumidified by contacting it with water in a spraying tower. In one process, a stream of air at 1250kg/h,37C and 50% relative humidity is to be cooled to 15C in a spray tower. The air is saturated as it leaves the tower. Liquid water exits the tower at 12C in which some is withdrawn, while the rest is cooled and recirculated. You may assume no heat is transferred from the tower to the surrounding. Use the appendix provided to solve for the following problems: (a) Dengan menggunakan maklumat diatas, lukis gambarajah aliran bagi proses yang dimaksudkan. Kemudian hitung kadar aliran air ( kg/h ) yang perlu disingkirkan daripada proses ini. Using the information provided above, draw a flow chart for the process. Then calculate the rate (kg/h) at which water must be withdrawn from the recirculation loop. (8 markah/marks) (b) Hitung tugasan haba untuk penyejuk dalam unit kW (Petunjuk: Anda boleh menggunkan imbangan tenaga keseluruhan bagi system ini sebagai jalan penyelesaian) Calculate the heat duty of the cooler in kW (Hint: You may use the overall energy balance of the system to solve this problem) (4 markah/marks)
