Pressurized air at a rate of 4.5 kg/s flows in a rectangular duct. The air pressure and temperature at a point in the duct is measured as 33 C and 250 kPa. The duct cross section is a rectangle of 50 cm by 20 cm. Find a) the volumetric flow rate, b) the mass flux, c) the average velocity at this location.

Liquid sodium enters the core of a liquid metal fast breeder reactor (LMFBR) at 400 C and leaves at 560 C. The reactor operates at 750 MW. Find the sodium flow rate.
