![Question:
A small fan in a closed insulated room
releases heat at the rate of 42 watts and
pushes the air at the rate of 9 m/s with a
mass flow rates of 1.2 kg/s. The room has
a heater that produces heat at the rate of
0.30 kJ/s as well as a computer that
produces 65 watts. Light bulbs in the
room produce up to 125 watts. The room
looses 0.32 kJ/s. Calculate the amount of
heat maintained in the room.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F38dd5e77-ccaf-4cc8-9b47-09dd2136f791%2Fc9448ab8-efe4-4424-8ca6-3d68c5e746f4%2F1iat45j_processed.jpeg&w=3840&q=75)
