Major and Minor Friction Pressure Losses in a Pipe Flow–Continued from the previous page Minor Pressure losses There are three methods for finding minor pressure loss in pipe fittings. 1. The equivalent length method——Equivalent length for each type of pipe fitting has been prescribed so that frictional pressure drop in that length can be calculated […]
Definition of Pressure, Its Units, Different Forms of Pressure, Absolute Pressure, Vacuum, Measurement of Pressure, Mechanical and Electrical Transducers PRESSURE OF A FLUID: NORMAL force of fluid per unit area. Its units are Pascal and bars. 1 Pascal = 1 N/m2 1 bar = 740 mm of Hg = 10 m of water 1atmospheric pressure = […]
Pressure Drop PRESSURE DROP It is difference of pressure between two points in a fluid flow. These two points can be at horizontal level or at different levels. (i) PRESSURE DIFFERENCE IS THE DRIVING FORCE FOR THE FLOW OF A FLUID. (ii) Likewise temperature difference is the driving force for heat transfer. (iii) Voltage difference […]
