Heat capacity mass flow rate
Web20 de feb. de 2024 · Figure 12.1.1: Flow rate is the volume of fluid per unit time flowing past a point through the area A. re the shaded cylinder of fluid flows past point P in a uniform pipe in time t. The volume of the cylinder is Ad and the average velocity is ¯ v = d / t so that the flow rate is Q = Ad / t = A¯ v. WebThe mass flow rate of exhaust gas and the percentages of gaseous products in it change as per changes in vehicle speed, road conditions, acceleration etc. The total mass of exhaust gas of engine can be calculated by using the following formula: ṁ exhaust = ṁa + ṁf Eq (1) Where, ṁa =mass flow rate of air in the engine cylinder
