How to Calculate Second Moment of ERH about Time Origin divided by Total Excess Rainfall?
Second Moment of ERH about Time Origin divided by Total Excess Rainfall calculator uses Second Moment of the ERH = Second Moment of the DRH-(Constant n*(Constant n+1)*Constant K^2)-(2*Constant n*Constant K*First Moment of the ERH) to calculate the Second Moment of the ERH, The Second Moment of ERH about Time Origin divided by Total Excess Rainfall formula is defined as the moment of effective rainfall hyetograph corresponding to the moment of Direct Runoff Hydrograph. Second Moment of the ERH is denoted by MI2 symbol.
How to calculate Second Moment of ERH about Time Origin divided by Total Excess Rainfall using this online calculator? To use this online calculator for Second Moment of ERH about Time Origin divided by Total Excess Rainfall, enter Second Moment of the DRH (MQ2), Constant n (n), Constant K (K) & First Moment of the ERH (MI1) and hit the calculate button. Here is how the Second Moment of ERH about Time Origin divided by Total Excess Rainfall calculation can be explained with given input values -> 441.2548 = 448-(3*(3+1)*4^2)-(2*3*4*10).
