In a heating system, cold outdoor air at 7°c flowing at a rate of 4 kg/min is mixed adiabatically with heated air at 66°c flowing at a rate of 5 kg/min. determine the exit temperature of the mixture. solve using appropriate software.

The exit temperature of the mixture is 39.7°.

Explanation:

Given that,

Outdoor temperature = 7°C

Flowing rate = 4 kg/min

Temperature = 66°C

Flowing rate = 5 kg/min

We need to calculate the exit temperature of the mixture

Using  balance equation for the system

Put the value into the formula

Hence, The exit temperature of the mixture is 39.7°.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
