How to Calculate grade at beginning of curve when elevation of point x distant from PVC is given?
grade at beginning of curve when elevation of point x distant from PVC is given calculator uses Grade at beginning of curve=(Elevation of point x distance from PVC-Elevation of PVC-(1/2)*Rate of change of grade*Distance of any point on the curve from the PVC^2)/Distance of any point on the curve from the PVC to calculate the Grade at beginning of curve, The grade at beginning of curve when elevation of point x distant from PVC is given is defined as the grade at the beginning(starting point) of the parabolic curve. Grade at beginning of curve and is denoted by _{1} symbol.
How to calculate grade at beginning of curve when elevation of point x distant from PVC is given using this online calculator? To use this online calculator for grade at beginning of curve when elevation of point x distant from PVC is given, enter Elevation of point x distance from PVC (E_{x}), Elevation of PVC (E_{0}), Rate of change of grade (R and Distance of any point on the curve from the PVC (x and hit the calculate button. Here is how the grade at beginning of curve when elevation of point x distant from PVC is given calculation can be explained with given input values -> -2500.25 = (25-50-(1/2)*50*100^2)/100.
