Air flows through a main duct at a mass flow rate of 4 kg/s. The main duct enters a junction that splits into branch ducts, one with a cross section of 20cm x 30cm and one with a cross section of 40cm x 60cm. If the mass flow rate in the large branch is 2.8 kg/s, what is the mass flow right in the small branch? If the density of air is p=1.16 kilograms per meter cube what is the velocity in each branch?
