What is mean by coefficient of discharge?

What is mean by coefficient of discharge?

In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge or efflux coefficient) is the ratio of the actual discharge to the theoretical discharge, i.e., the ratio of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an identical …

What is the formula of discharge?

The flow rate of a stream is equal to the flow velocity (speed) multiplied by the cross-sectional area of the flow. The equation Q=AV (Q=discharge rate, A=area, V=velocity) is sometimes known as the discharge equation.

What increases river discharge?

As the rain starts to get heavy, the soil may be saturated, thus there is an increase in surface run off. This causes water to start flowing into the river channel, causing the level of discharge to increase, making the line go up positively.

What is design discharge?

Design discharge is the maximum flood that any hydraulic cross section allows to pass safely without inundation problems on the channel banks. Figure 7.1 indicates the bank-full level of a flood occurrence in a cross section, Fig.
