The velocity of air in the diverging pipe
WebA converging duct (dA < 0) now decreases the velocity of the flow and a diverging duct (dA > 0) increases the velocity of the flow. At Mach = 1, a special case occurs in which the duct area must be either a maximum or minimum. For practical purposes, only a minimum area can accelerate flows to Mach 1 and beyond. Web6. Air enters a 15-m-long, 4-cm-diameter adiabatic duct at V 1 =70 m/s, T 1 =500 K, and P 1 =300 kPa. The average friction factor for the duct is estimated to be 0.023. Determine the Mach number at the duct exit, the exit velocity, and the mass flow rate of air. Solution: Take the properties of air to be k = 1.4, c p

(a) Determine the local acceleration at points (1) and (2). … WebThe choked velocity is observed upstream of an orifice or nozzle. The upstream volumetric flow rate is greater than the downstream condition because of the higher downstream density. The choked velocity is a function of the upstream pressure but not the downstream.
