The error in discharge (dQ/Q) with respect to the error in the measurement of head (dH/H) through a triangular notch is given by:
1
\(\frac{\mathrm{dQ}}{\mathrm{Q}}=\frac{3}{2}\left(\frac{\mathrm{dH}}{\mathrm{H}}\right)\)
2
\(\frac{\mathrm{dQ}}{\mathrm{Q}}=\frac{5}{2}\left(\frac{\mathrm{dH}}{\mathrm{H}}\right) \)
3
\(\frac{\mathrm{dQ}}{\mathrm{Q}}=\sqrt{\frac{5}{2}}\left(\frac{\mathrm{dH}}{\mathrm{H}}\right) \)
4
\(\frac{\mathrm{dQ}}{\mathrm{Q}}=2\left(\frac{\mathrm{dH}}{\mathrm{H}}\right)\)
