    PRESSURE TRANSMITTER LOCATION

    For steam flow the taps should be on the side and the transmitter mounted below. The lead lines (impulse lines) should be filled with water (condensate). The lead lines should have no high spots where gases can collect and to allow gases liberated to flow back to the process. For long lead lines...

    MDEA Viscosity

    For newtonian fluids Andrade's equation is useful for estimating viscosity at a temperature. u = AL exp BL/T From two known values of viscosity constants AL and BL can be determined BL = (T1 * T2 * ln(u1/u2))/(T2 - T1) AL = u1/exp (BL/T1) Where T is absolute temperature Using the 2 points...
