4. The discharge coefficient C, of an orifice can be found by collecting the water that flows through during a timed interval when it is under a constant head h. The formula is W Ca = 1pA v 2gh Find C, and its possible error if: W == 865 + 0.5 1bm A = nd-/4 d = 0.500 + 0.001 in f - 600.0 + 2 s 9 = 32.17 + 0.1% ft/s2 p = 62.36 + 0.1% Ibm/ft h = 12.02 + 0.01 ft considering both the following: (a) The errors are the absolute limits. (b) The errors are + 3s limits. 5. what percentage error may be expected in measuring the voltage across R, if R, = R, = R, = R. = Rx = 100 and Rm = 1,000 Q? If Rm = 10,000 0?
