weir A series of depth and discharge measurements are made on a sharp-crested rectangular weir in order to establish the coefficient of discharge for the weir. Experimental values are used to plot log(H) against log(Q) and generate a line of best fit. The resulting line passes through the points (-699/1000, -0.393) and (-131/1000, 0.451). The weir is 2.5 m wide. Give your answers to 3 d.p. (a) Calculate the gradient of the line of best fit (b) Calculate the value of log(Q) for which the line of best fit crosses the log(Q) axis (i.e. the intercept) (c) Calculate cd, giving your answer to 3 d.p.
