Specific heat ratio ν - kinematic viscosity Result of fluid particles colliding to each other and moving at different velocities in terms of area per square unit of time μ - dynamic viscosity Result of fluid particles colliding to each other and moving at different velocities in terms of mass...
Cc= Throat velocity (m/sec) r = pressure ratio = p1/ p2 rc= critical pressure ratio A2= outlet area (m2) Ac= throat area (m2) n = index of expansion m = mass flow rate (kg/m2)
Convergent-Divergent Nozzle Flow Velocity and Area Equation and Calculator Throat Velocity Equation: Values of the index n and the critical pressure ratio r, for different fluids are given in the table below. Throat Area Equation: Critical Pressure Ratio Equation: Nozzle Outlet Velocity Equation...
2) When the t/T ratio for a loaded nozzle is less than 1.0 and WRC 107/297 is considered for use. 3) When the nozzle is pad reinforced and WRC 107/297 is considered for use. 4) When the number of full range pressure cycles is greater than 7000 cycles and the nozzle is subject ...
The test engine had a compression ratio of 10:1, which is usual for a CNG engine having a turbocharging system. The engine had a 4-valve system with an intake and exhaust valve overlap of 23 CAD at 0 mm valve lift for air intake scavenging purposes. The air intake pressure was adjusted...
