The total energy of the fluid is conserved as a consequence of the law of conservation of energy. A piping system containing many pipe fittings and joints, tube convergence, divergence, turns, surface roughness, and other physical properties will also increase the head loss of a hydraulic system.Īlthough the head loss represents a loss of energy, it does not represent a loss of total energy of the fluid. The head loss that occurs in pipes is dependent on the flow velocity, pipe diameter, and length, and a friction factor based on the roughness of the pipe and the Reynolds numberof the flow. The head loss (or the pressure loss) due to fluid friction (H friction) represents the energy used in overcoming friction caused by the pipe walls. H friction = head loss due to fluid friction (m) ![]() The following equation is one form of the extended Bernoulli equation. The resulting equation referred to as the extended Bernoulli’s equation is very useful in solving most fluid flow problems. The Bernoulli equation can be modified to take into account gains and losses of the head. The simplified Bernoulli equation must be modified to deal with both head losses and pump work. In reality, one purpose of pumps incorporated in a hydraulic system is to overcome the losses in pressure due to friction.ĭue to these restrictions, most practical applications of the simplified Bernoulli equation to real hydraulic systems are very limited. The total head possessed by the fluid cannot be transferred completely and is lossless from one point to another. In reality, friction plays a crucial role.
