Q1 The following is the equation of flow over a rectangular weir. q=0.415(L0.2h)h1.52g Where, q=volumetricflowrate,ft3/sL=crestheight,fth=weirhead,ftg=accelerationofgravity,ft/s2 a) Explain in details that the equation is dimensionally consistent. b) Calculate the volumetric flow rate in m3/min if the crest height is 2.45m and weir head is 1yd. c) Drive and equation with q in m3/m,L in m and h in yd. d) Repeat part (b) using the derived equation in part (c)
