2. A pitot tube is inserted in an air flow (at STP, i.e. Temp-20C & p- 760 mm of Hg) to measure the flow speed. The tube is inserted so that it points upstream into the flow and the pressure sensed by the pitot tube is stagnation pressure. The static pressure is measured at the same location in the flow using a wall pressure tap, If the pressure difference is 30 mm of mercury, determine the flows peed. Assume the flow is incompressible and density of air at STP is 1.23Kg/m 2. A pitot tube is inserted in an air flow (at STP, i.e. Temp-20C & p- 760 mm of Hg) to measure the flow speed.
