If, however, the … WebFeb 16, 2024 · It simply states that the rate of the inlet of mass in a system is equal to the rate of the outlet of mass from the system. It can be mathematically expressed as. A 1 V 1 = A 2 V 2. Here, A 1 = cross-sectional area of entrance section. A 2 = cross-sectional area of exit section. V 1 = Velocity while entering section 1.

WebAnswer (1 of 2): Isentropic relations are used to show the total condition of the flow Hence we use "t" in every such equation of compressible flow The Mach number M is the ratio of the speed of the flow "v" to the speed of sound "a". We can determine the value of the constant by defining total... WebIf the velocity of the fluid is above 100 m/s, then we can regard the flow as incompressible, let's assume tat this is the case for section 2 (smaller surface area therefore greater velocity). If the flow is steady, then, we can say that the mass flow rate (that is rho U A) would remain constant.
