Assignment Help Mechanical Engineering

A hair dryer consumes 1200w of electric power when running the inlet volume flow rate and the exit velocity of air are to be determined?

in ---> P1=100kPa, T1=22 celsius

out--> A2=60 cm^2, T2=47 celsius

R sub air = 0.287 kPa*m^3/kg*k

C sub p=1.005 kJ/kg*k
