Pure ethane is burned completely with preheated 20% excess air. The combustion product gas passes continue on to the furnace. The following data are recorded for the preheater inlet and outlet streams: Flow rate in (LIS) Tin (°C) Pin (tor) Flow rate out (US) Tout (°C) Pout (tor)
Product gas 945 830 1.98 x 10^5 850 912
Air 5.53 x10^4 30 684 836

The temperature of the air leaving the preheater is not known because the thermocouple mounted in that pipe has malfunctioned.

Requried:
Calculate the molar flow rates (mol/s) of the two streams flowing through the preheater and the temperature of the air leaving the preheater.
