<span>mV^2 = 2Fb*x </span>
<span>x = mV^2/2Fb = 1000*16.7^2/16.000 = 17.43 meters</span>
Answer:
H_w = 2.129 m
Explanation:
given,
Width of the weir, B = 1.2 m
Depth of the upstream weir, y = 2.5 m
Discharge, Q = 0.5 m³/s
Weir coefficient, C_w = 1.84 m
Now, calculating the water head over the weir
now, level of weir on the channel
H_w = y - H
H_w = 2.5 - 0.371
H_w = 2.129 m
Height at which weir should place is equal to 2.129 m.
A). Scale.
You CAN measure volume with all the following except a scale.
Answer:
A computer is a machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Modern computers have the ability to follow generalised sets of operations, called programs. These programs enable computers to perform an extremely wide range of task
