) for high-pressure steam. Steam near the saturation line behaves as a real gas, and its specific heat ratio changes drastically during expansion. Units: W_m in kg/h, P_m in bara

Enable iterative calculations in Excel ( File > Options > Formulas > Enable iterative calculation ). Alternatively, replace the circular cell reference with a clean VBA root-finding algorithm (like a Newton-Raphson loop) to calculate the pressure recovery cleanly. Steam near the saturation line behaves as a

Real-world diffusers aren't perfect. Apply an efficiency coefficient (usually 0.65 to 0.80) to your pressure recovery calculations. Step 4: Check for Critical Flow Ensure the discharge pressure ( Pdcap P sub d

) is calculated using the critical flow equation for compressible fluids:
