An engineering laboratory experiment uses a triangular weir in an open channel to measure flowrate. The nominal weir angle is 90°. In a certain test, the head of water above the weir was 4 in. The uncertainty in the weir angle is ±2° and the uncertainty in the depth measurement is ±0.05 in. Compute the flowrate and the uncertainty in the flowrate.
