One stream passes through a heating section and leaves it with a relative humidity of 25%. The conditions of the other stream that bypasses the heater remains unchanged. The two streams are then mixed to produce the supply air stream at 24°C. The pressure is constant at 101.3 kPa. Determine (i) heat input by the heating coil, and (ii) the mass flow of air through the bypass section. 100 105 110 115 120 kJ/kg(d.a) 30 95 29 -1.0-0o 28 -0.8 10.00.7 8.0 E-10.0 1.5+-5.0 2.0- -2.0 18+-1.0 90 85 27 5.0+0.5 F0.4 6.0 F0.6 26 F0.0 -4.0- -2.0- "F1.0 1.0 SENSIBLE HEAT TOTAL HEAT Qt 80 25 75 24 23 70 22 HP HUMIDITY RATIO dw 65 ENTHALPY 21 60 55 20 19 18 50 17 45 16 - - - 15 40 14 35 13 30 12 25 11 40% 10 20 9 15 30% 8 10 7 5 20% 5 4 10% 3 -5 2 1 -10 -10 -5 0 5 10 15 20 25 30 35 40 45 50 Dry Bulb Temperature, °C.
