A.M. is a 43-year-old male who presents to the emergency department with complaints of severe pain in the right posterior lumbar area. He has a history of a cystocele two years ago which was repaired. A urinalysis was ordered, which showed hematuria and protein in the urine. The nephrologist suspects that Mr. M has either pyelonephritis or a renal calculus. Since the patient doesn't complain of fever, dysuria, or polyuria, a UTI seems unlikely. A retrograde urogram was ordered to visualize the urinary tract as well as a renogram to evaluate the kidney function. A kidney stone was confirmed, and the patient was sent to the urological procedure room for an extracorporeal shock wave lithotripsy. After the procedure, the patient reported relief from the pain with only minor discomfort remaining.

Q8. a) The outdoor and indoor conditions of the air in a cinema hall of 1000 capacity are 11°C & 70%RH and 20°C & 60%RH.The amount of air supplied is 0.3m³/min. The required conditions are achieved first by heating, then by adiabatic humidifying and finally by heating. The condition of the air coming out of the humidifier is 75%RH.Find the following: (i) Heating capacity of the first heater in kW and condition of the air coming out of the first heater. Also find the surface temperature required if the bypass factor is 0.3 (ii) Heating capacity of the second heater in kW and its bypass factor if surface coil temperature of the coil is maintained at 22°C. (Use Psychometric Charts) b) Atmospheric air at 30°C and 60% is conditioned to 20°C DBT and 100%RH using a cooling coil. If the quantity of air flow is 100m³/min, find the following: 1) Capacity of cooling coil in TR 2) Dew point Temp & Wet Bulb Temperature (Use analytical approach) (6, 4)
