QUESTION:

Orifice meters are used to measure the flow rate of a fluid. In an experiment, the flow coefficient K of an orifice is found by collecting and weighing water flowing through the orifice during a certain interval while the orifice is under a constant head. K is calculated from the following formula: K= M tAp(2g Ilh )112 The values of the parameters have been determined to be as follows, with 95 % confidence: Mass Time Density Diameter Head M = 393.00 0.03 kg t = 600.0 1 s p = 1000.0 0.1 % kglm3 d = 1.270 0.0025 em (A is area) Ah = 366.0 0.3 em Find the value of K, its uncertainty (with 95% confidence), and the maximum possible error.
