Why is temperature required in liquid and gas flow systems?

Liquid systems do not have this problem. Temperature measurement is required in both liquid and gas flow measurement systems due to the fact that both liquid and gas density vary with temperature. So a continuous measurement of the temperature of the process is required in order to compensate for this variation.See all results for this questionWhat is the diameter of a turbine flow meter?The general guidelines suggested by manufacturers of turbine flow meters are 15-20 straight pipe diameters (inclusive of the strainer) straight pipe runs upstream and 5 straight pipe diameters straight pipe runs downstream.See all results for this questionWhat is pipe temperature measurement?That technique utilizes a temperature measurement on the outside surface of the pipe in which the fluid is flowing and assumes that that value is the temperature of the fluid. The goal of the work reported here is to quantify the possible differences between the measured pipe wall temperature and the temperature of the flowing fluid.See all results for this question

What is differential pressure flow meter?

Both liquid and gas density change with temperature as a result, they are compensated for in a differential pressure flow measurement system like the orifice plate flow meter. 1.

Major losses are associated with frictional energy loss that is caused by the viscous effects of the fluid and roughness of the pipe wall. Major losses create a pressure drop along the pipe since the pressure must work to overcome the frictional resistance. The Darcy-Weisbach equation is the most widely accepted formula for determining the energy loss in pipe flow.
