How do you calculate river discharge?

Discharge = V x D x W If length is measured in feet and time in seconds, Discharge has units of feet3/sec or cubic feet per second (cfs). Depth times Width gives the cross-sectional area. The shape of the channel is important because of the reduction in velocity due to friction along the channel margins.

How is stream discharge measured?

Discharge is the volume of water moving down a waterway per unit of time. It is most commonly expressed in cubic feet per seconds or gallons per day. To calculate discharge, multiply the area of water in a channel cross section by the average velocity of water in that cross section.

How do you calculate the discharge of water in a canal?

Referring to the formula Q = V ´ A, it should be clear that for the same discharge and a smaller average flow velocity, the area of the wetted cross-section has to increase. Thus, due to a lower flow velocity, the water depth will increase and the canal will risk overtopping.

How do you calculate the discharge of water?

The discharge ( Q) can be calculated by the following formula: Q = V ´ A where: Q is the Discharge in m3/s; V is the Average Flow Velocity in m/s; and A is the area in m2of the Wetted Cross-section.

How to calculate discharge carrying capacity of river Tapi?

In order to estimate discharge well known and used for several river in USA [10] Manning‟s formula is applied which gives river flow velocity V =1 n R 2 3S 1 2(2) Where V = flow velocity (m/s), n = river bed roughness, R = hydraulic radius = A / P (m) and S = the river slope(m/m).

How to calculate the carrying capacity of a river?

Where V = flow velocity (m/s), n = river bed roughness, R = hydraulic radius = A / P (m) and S = the river slope(m/m). In order to find out discharge carrying capacity of each river cross-section manually, above method is used but the work becomes time consuming.

How is the discharge formula for a capacitor calculated?

It computes the amount of voltage the capacitor has discharged, which is what the capacitor discharge formula, above, calculates and it computes the amount of voltage remaining in the capacitor, which is equal to the initial voltage the capacitor has minus the amount of volts it has discharged.
