When a fluid flows through a sharp bend, low pressures may

developin localized regions of the bend. Estimate the

minimumabsolute pressure (in psi) that can develop without

causingcavitation if the fluid is water at 160 oF.

    38.6 kPa.

    Explanation:

    Liquids cavitate when the pressure falls below their vapor pressure for the temperature they are.

    Water at 160F has a vapor pressure of:

    pv = 38.6 kPa

    So the minimum absolute pressure that can develop without causing cavitation would be just above 38.6 kPa.
