the average annual precipitation on catchement of 350km sequare is 200 mm and the runoff is 9%.compute average flow at the out let of the catchement in m cubic per second?
and plans made to extract 10 power of 8 meter cubic ground water annualy .this water will be transported to a towen else where ,out side the catchement would you recommend this plan to be executed?why?
To calculate rainwater runoff for determining culvert size, you first need to assess the drainage area, including its size and land use characteristics, which affect runoff coefficients. Utilize the Rational Method, where runoff (Q) is calculated using the formula Q = CiA, with C being the runoff coefficient, i as the rainfall intensity (in inches per hour), and A as the area (in acres). After determining the peak runoff, consider factors such as culvert slope, material, and local regulations to select an appropriate culvert size that can handle the expected flow without causing flooding or erosion.
To calculate rainfall using the Thiessen polygon method, you first need to divide the area into polygons based on rain gauge locations. Then, calculate the area of influence of each rain gauge within its polygon. Finally, you can determine the weight of each rain gauge based on its influence area, which is used to calculate the average rainfall for the entire region.
You can calculate the drag coefficient by using the formula Cd = Fd / (0.5 * ρ * A * V^2), where Cd is the drag coefficient, Fd is the drag force, ρ is the air density, A is the reference area, and V is the velocity of the object. Given these values, you can rearrange the formula to solve for the drag coefficient.
To calculate the extinction coefficient of a protein, you can use the formula: Extinction coefficient (A11cm) / (number of amino acids x molecular weight). A11cm is the absorbance at 280 nm for a 1 cm path length. This value can be determined experimentally using a spectrophotometer.
To find the coefficient of static friction on an incline, you can use the formula: coefficient of static friction tan(angle of incline). Measure the angle of the incline using a protractor, then calculate the tangent of that angle to find the coefficient of static friction.
To calculate the protein extinction coefficient for a given protein sample, you can use the formula: Extinction coefficient (Absorbance at 280 nm) / (Concentration of protein in mg/ml). The absorbance at 280 nm can be measured using a spectrophotometer, and the concentration of the protein can be determined using methods such as the Bradford assay or the bicinchoninic acid (BCA) assay.
You can use the correlation coefficient to calculate the RMSE value using the Microsoft Excel. The correlation coefficient is used to establish the relationship between the values in question.
The coefficient of variation should be computed only for data measured on a ratio scale, as the coefficient of variation may not have any meaning for data on an interval scale. Using relative values instead of absolute values can cause the formula to give an incorrect answer.
The drag coefficient (Cd) can be calculated using the formula: Cd = (2 * Drag Force) / (ρ * A * V^2), where ρ is the fluid density, A is the reference area, and V is the velocity. If drag force is not known, Cd can be determined experimentally by measuring the drag force at different velocities and using the above formula to calculate Cd.
To determine the coefficient of static friction, you can conduct an experiment by gradually increasing the angle of an inclined plane until an object on the plane just begins to move. You can measure the angle at which this occurs and use it to calculate the coefficient of static friction using the formula: coefficient of static friction = tan(angle).
The coefficient of kinetic friction can be calculated using the formula: coefficient of kinetic friction = force of kinetic friction / normal force. The force of kinetic friction can be found using the formula: force of kinetic friction = coefficient of kinetic friction * normal force. Given the force of 31N and normal force equal to the weight of the crate (mg), you can calculate the coefficient of kinetic friction.
Rainfall is quantified and measured accurately using rain gauges, which are instruments that collect and measure the amount of precipitation that falls in a specific area over a certain period of time. The collected data is then used to calculate the average rainfall in that area.
