Question
Asap,
Air is heated to 2atm and 227 °C while
circulating through a 3.0 cm diameter tube at
a speed of 10 m/s. Calculate the heat
transferred per unit length of tube if a
constant heat flow condition is maintained in
the wall, the temperature of the wall being 25
°C higher than the temperature of the air
throughout the entire tube. How much would
the average temperature increase in 3m
length of pipe?
