Write the relation between head loss and pressure loss. Here, is the density of the flowing fluid, is the pressure loss, and g is the acceleration due to gravity. Therefore, head loss of the flowing fluid is directly proportional to pressure loss.
How is head loss related to pressure loss?
In fluid flow, head loss or pressure loss reduces the total head (sum of the potential head, velocity head, and pressure head) of a fluid caused by the friction present in the fluid’s motion.
What does head loss mean in fluid mechanics?
Head loss is a measure of the reduction in the total head (sum of elevation head, velocity head and pressure head) of the fluid as it moves through a fluid system. The head loss is inversely proportional to the diameter of the pipe.
What is the relationship between head loss and flow rate?
The greater the flow rate, the greater the rate of head loss increases. Using the doubling flow rate rule, the 200 gpm flow rate with its head loss of 2.3 feet would result in a head loss of 9.2 feet instead of the calculated value of 8.5 feet.
What are the reasons for minor head losses in a pipe?
Major Head Loss – due to friction in pipes and ducts. Minor Head Loss – due to components as valves, fittings, bends, and tees.
What does head loss represent?
Head loss refers to a measurement of the energy dissipated in a fluid system due to friction along the length of a pipe or hydraulic system, and those due to fittings, valves and other system structures. Head loss is unavoidable in real fluid systems containing liquids or gases.
What is water head loss?
The head, pressure, or energy (they are the same) lost by water flowing in a pipe or channel as a result of turbulence caused by the velocity of the flowing water and the roughness of the pipe, channel walls, or fittings. Water flowing in a pipe loses head as a result of friction losses.
How do you calculate head pressure loss?
How to calculate head loss:
- Head Loss (Pc) = [Equiv. pipe length + Installation pipe length] x Pc \% / 100 x Corrector.
- Equivalent pipe length. This refers to the equivalent length of the non-straight pipework when compared to straight pipes (in metres).
- Installation pipe length.
- Pc \% and Corrector.
What is loss of head of water?
What affects head loss?
Overall head loss in a pipe is affected by a number of factors which include the viscosity of the fluid, the size of the internal pipe diameter, the internal roughness of the inner surface of the pipe, the change in elevation between the ends of the pipe, bends, kinks, and other sharp turns in hose or piping and the …
What happens to the head loss when the flow rate is doubled?
Explanation: If the flow rate is doubled, the head loss increases by a factor of four. Since, the head loss is directly proportional to the square of the flow rate.
What is the dependence of head loss upon velocity or flow rate in the laminar and turbulent regions of flow?
For laminar flow, the head loss is proportional to velocity rather than velocity squared, thus the friction factor is inversely proportional to velocity.
What is head loss in fluid flow?
In fluid flow, head loss or pressure loss is a reduction in the total head (sum of potential head , velocity head , and pressure head) of a fluid caused by the friction present in the fluid’s motion. Minor Head Loss – due to components as valves, bends…
What is head loss and how is It measured?
The head loss that occurs in the components of a flow path can be correlated to a piping length that would cause an equivalent head loss. Head loss is a measure of the reduction in the total head (sum of elevation head, velocity head and pressure head) of the fluid as it moves through a fluid system. Head loss is unavoidable in real fluids.

What factors increase the head loss of a hydraulic system?
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. Although the head loss represents a loss of energy, it does does not represent a loss of total energy of the fluid.
