A duct of diameter 0.8 m carries gas (p = 1.3 kg/m³). At one point, the duct diameter reduces to 0.74 m. Starting from Bernoulli's equation, estimate the velocity of flow in the reduced section, and the mass flow rate (=pQ) through the duct if the pressure difference between a point upstream of the reduction and another point at the reduction is equivalent to 30 mm of water.
