A differential pressure transmitter is calibrated to measure

A differential pressure transmitter is calibrated to measure the flow of a liquid. Explain what will happen if the fluid is not pure liquid but contains some vapor bubbles.

Solution

The boiling point of substance is the temperature at which the vapor pressure of liquid equals to the pressure surrounding the liquid and the liquid changes in to vapor.the bowling point of liquid various depending upon the surrounding environmental pressure. A liquid in a partial vaccum has lower boiling point than when that liquid is at atmospheric pressure. A liquid at high pressure has a higher boiling point than when liquid is atatmospheric pressure.at normal point IG a liquid is the special in which the vapor pressure of liquid equal to atmospheric pressure at sea level.at that temperature the vapor pressure of liquid becomes to overcome the atmospheric pressure and allow bubbles vapor to form in side the liquid.
