entering velocity 15 m/s and exit velocity 23 m/s. Also entering pressure 1,25 and exit pressure 1. Also, we have 15 *C temperature. Thus, we need to break up system sections, don't we.?
And we can do mass and energy balances??
thank u for answering.. in the problem, there is no mass for air. There is just enter velocity of air to the tube. Can we convert from velocity to the mass flow rate.?
l have a tube. and air enters the tube at a certain temparature and pressure. the air is threated as an ideal gas. Also, we know the exit pressure of the gas. In additon to those, we know radious of the tube.. How do we find the heat transfer rate.?
