Water flow regards the quantity of this fluid medium per a unit of time. In SI units it would be liters per second (lps), and in American it is commonly measured in gallons per minute (gpm).
The mass of water used in the first six minutes depends on the rate of flow of water. If we know the flow rate, we can calculate the mass using the formula: Mass = flow rate x time.
A weir gauge is typically used to measure the flow rate of water in open channels such as rivers or streams. It works by allowing water to flow over a weir structure, and the height of the water level above the weir can be used to calculate the flow rate using established equations.
That depends on what information is provided. If you don't have any information, you may actually need to measure the speed of the water; or you may want to measure the flow (for example, in liters per second), and the pipe diameter, and then calculate the speed from that.
To calculate the chilled water coil capacity using the airside performance, you would divide the airside thermal capacity by the ADP (Approach Design Point) temperature difference. This will give you the required chilled water flow rate to meet the cooling load of the airside system.
This is the ratio volume/time.
The formula to calculate the garden hose flow rate is: Flow rate (Cross-sectional area of the hose) x (Water velocity)
To calculate water pressure from flow rate, you can use the formula: Pressure Flow Rate x 0.433 x Height. This formula takes into account the flow rate of the water in gallons per minute and the height of the water column in feet. By multiplying the flow rate by 0.433 and the height, you can determine the water pressure in pounds per square inch (psi).
To calculate water pressure based on the flow rate, you can use the formula: Pressure Flow Rate x Density x Gravity x Height. This formula takes into account the flow rate of the water, the density of water, the acceleration due to gravity, and the height of the water column. By plugging in the values for these variables, you can determine the water pressure.
You can calculate the velocity of water in a channel using the formula v = Q/A, where v is the velocity, Q is the flow rate of water, and A is the cross-sectional area of the channel through which the water is flowing. By knowing the flow rate and the cross-sectional area of the channel, you can determine the velocity of water.
The mass of water used in the first six minutes depends on the rate of flow of water. If we know the flow rate, we can calculate the mass using the formula: Mass = flow rate x time.
(to check the flow rate of water ... calculate the pressure drop
Before you can calculate the flow, you must also have the pipe size and its coefficient of friction.
The question is incomplete, therefore this answer is..............
A weir gauge is typically used to measure the flow rate of water in open channels such as rivers or streams. It works by allowing water to flow over a weir structure, and the height of the water level above the weir can be used to calculate the flow rate using established equations.
To calculate the velocity of water in a pipe, you can use the formula: velocity flow rate / cross-sectional area of the pipe. The flow rate can be measured in liters per second or cubic meters per second, and the cross-sectional area is the area of the pipe's opening. By dividing the flow rate by the cross-sectional area, you can determine the velocity of the water flowing through the pipe.
Most plumbing or pipefitting suppliers have charts that show what size pipes you need to provide the proper flow rates at various pressures.
