Water Resources Engineering Laboratory Flow Over a Dam Spillway Prepared by Redahegn Sileshi 3 5. Calculations • Calculate the total energy head He. • Graph the experimental data (ln Q vs ln H e) and fit a linear equation ( y = mx + b ). • Calculate m=slope of the linear equation , ln(k)=y-intercept of the linear equation , k, and C .

Friction loss is the loss of energy or “head” that occurs in pipe flow due to viscous effects generated by the surface of the pipe. This energy drop is dependent on the wall shear stress (τ) between the fluid and pipe surface. The shear stress of a flow is also dependent on whether the flow is turbulent or laminar.

suggested that the energy losses in any pipe fitting can be broken down into three components: entry loss, exit loss and friction losses. Saho et al. (2009) investigated the accuracy of numerical modelling of the laminar equation to determine the friction factor of pipe. The numerical differential equation is iterated
Jun 19, 2014 · It is the only [inspection device] small enough to fit inside of a 4-inch pipe. Many modern water systems are built using 4-inch pipe, so being able to inspect this pipe diameter is very important. Another important element is the reporting mechanism. Using GPS, this [device] can specifically locate and report the location of a leak in a pipe.”
Energy input to the gas or liquid is needed to make it flow through the pipe or conduit. This energy input is needed because there is frictional energy loss (also called frictional head loss or frictional pressure drop) due to the friction between the fluid and the pipe wall and internal friction within the fluid.

component. Hence these losses are referred to as local losses or minor losses. It should be remembered that these losses sometimes are the dominant losses in piping system and hence the term minor losses is a misnomer often. Experimental procedure: ­ 1. Select the required pipe line 2.
used as intermediate medium), and steady state can be assumed, reducing the generic energy balance to: openings t,e e 1 1 2 2 time ∆= ++Ε W Q h m mh m h∑ ∫ d0 → = ∆+ ∆ (1 ) where the total enthalpy h t has been approximated by enthalpy (i.e. negligible mechanical energy against thermal energy), and ∆ means output minus input.

It also shows that if the gas is cooled to absolute zero then the energy of the molecules is at the lowest energy state and therefore cannot generate any pressure. Pressure Law Example: Using the example of the sealed cylinder above the pressure of gas is recorded as 1.0 x 10 5 N/m 2 at a temperature of 0°C.

This energy drop is dependent on the wall shear stress (τ) between the fluid and pipe surface. ...

D = Diameter of pipe. 2) Minor energy losses: The loss of energy due to change of velocity of the flowing fluid in magnitude or direction is called minor loss of energy. The minor loss of energy includes the following cases (a) Sudden expansion of pipe: The head loss due to sudden expansion equation is he = (V 1-V 2) 2 /2g.
Nikuradse equation (rough pipe): = 1.74 + 2.0310 2 In addition, a part from the energy loss due to friction, sudden change of the cross-section area or tube fitting attached to the pipe flow system might also cause energy loss. These losses are called minor loss or form loss due to pipe flow crosssection area.
