STATIC HEAD is the vertical distance that the liquid has to be lifted.įRICTION HEAD is due to the fittings and size of the pipe. Please Note: Supplier/vendor terminology is HEAD and users terminology is pressure. In both the cases pressure is required to make this work. This may be filling a tank at higher level or circulating a liquid. ![]() Pumps: The objective of pump is to trasfer liquid from source to a destination. ![]() In general, fluid in U tube Manometer will be Mercury, density of Mercury is 13600kg/m3. How to find pressure drop if U tube Manometer is installed and we know reading of Manometer.ĭelp=delrho*g*h this is similar to rho*g*h On substituting we will get P2 = 86.62 Kpa which is lower than the inlet pressure.Ĭontinuity and Bernouli equations are basic equations that are used in calculating Flow meters velocities (Venturi / Orifice meter). Inlet conditions of water flowing in a pipe with a conditions of 1.2 m/s and having 130 Kpa and its height is 2m and the outlet of the pipe is at 4m height and the outlet velocity is 7m/s. If the tank is open to atmosphere then pressure terms will get cancel. Second Example is Leak from a tank: V1(Velocity of tank) =0 because the fluid wont move and only the V2 is in motion. One example is if inlet and outlet of a pipe is in a same height then Potential energy term will cancel out. This equation can be modified in to simple cases i.e many terms will get cancel according to the given problem. P1+Rho1*g*h1+1/2Rho1*V1^2 = P2 + Rho2*g*h2+1/2Rho2*V2^2ġst term is pressure energy term, 2nd term is potential energy term and third is kinetic energy term. There is an extension of this equation is Bernoulis Equation most famous energy balance equation. ![]()
