Diverging duct
WebA pitot static probe is placed in a converging-diverging duct through which air flows. The duct is fed by a reservoir kept at $20^{\circ} \mathrm{C}$. If the probe reads a static pressure of $75 \mathrm{kPa}$ and a stagnation pressure of $100 \mathrm{kPa}$ at a location where the area is $0.00645 \mathrm{m}^{2},$ what is the local velocity and ... WebGas flows through a converging-diverging duct. At point "A'' the cross-sectional area is 50 [cm2] and the Mach number was measured to be 0.4. At point B in the duct the cross …

One-dimensional (1-D) flow refers to flow of gas through a duct or channel in which the flow parameters are assumed to change significantly along only one spatial dimension, namely, the duct length. In analysing the 1-D channel flow, a number of assumptions are made: • Ratio of duct length to width (L/D) is ≤ about 5 (in order to neglect friction and h…
