The discharge over a triangular notch can be written as
Q = (8/15) Cd (2g)0.5 tan(θ/2) H5/2
If an error of 1% in measuring H is introduced determine the corresponding error in the computed discharge.
A right angled triangular notch is used for gauging the flow of a laboratory flume. If the coefficient of discharge of the notch is 0.593 and an error of 2 mm is suspected in observing the head, find the percentage error in computing an estimated discharge of 20 L/s.

Is a sewing needle magnetic or non magnetic? Answer:- When you purchase it in the store it isn't magnetized but if you rub it with a magnet it becomes magnetic.
Relative velocity of a boat in a river flowing at a given velocity horizontally Ans) assume the river to be stopped and measure relative velocity of boat and find angle.
Do fibers have losses? Everything in the universe is inefficient. It means that while a measured amount of something enters in a system, less comes out than initially went in.
