From my simulation, at a location, I have static pressure(6.8459e+05 Pa),rho(962.5 kg/m^3) , velocity-U(23.2738),velo-V(-0.1655) gamma water(2.35) All in SI unit.

The total pressure from bernoulli equation and isentropic relation are different.

Bernoulli’s: 9.4552e+05

Isentropic: 6.8477e+05

The problem is with mach number. Since the speed of sound of water is high(>1000), the isentropic equation think the total pressure is very much close to total pressure. Is anyone know why the Bernoulli's is giving such high total pressure?

PS: The simulation is 2D inviscid and fluid is water and no phase transfer yet.
