Given:
The SPCS83 state plane coordinates of points A and B are tabulated below.
Point | E(m) | N(m) |
A | ||
B |
Calculation:
Write the Equation for Elevation factor.
Here,
Assume, the mean orthometric height as
Substitute
Calculate the combined factor using formulae.
Substitute
Write the expression to calculate the grid distance.
Write the Expression to calculate ground distance.
Substitute
Calculate the angle of grid line.
Substitute
The line AB is lies in first quadrant, origin at A. In this case, the azimuth of line can be calculated by subtracting the angle of line from
Substitute
Conclusion:
Thus, the combined factor for the line is
Thus, the geodetic azimuth is
Thus, the ground distance in meters is

- 6. A lake with no outlet is fed by a river with a constant flow of 1200 ft3/s. Water evaporates from the surface at a constant rate of 13 ft3/s per square mile of surface area. The surface area varies with the depth h (in feet) as A (square miles) = 4.5 + 5.5h. What is the equilibrium depth of the lake? Below what river discharge (volume flow rate) will the lake dry up?arrow_forwardProblem 5 (A, B, C and D are fixed).
