Answer:
ratio = 412
speed of wheel = 13.63
Explanation:
given data
head h = 91.5 m
discharge Q = 0.04 m³/s
wheel rotates N = 720 rpm
velocity coefficient Cv = 0.98
efficiency of the wheel η = 80 %
ratio of bucket speed to jet speed = 0.46
to find out
wheel to jet diameter ratio and power specific speed of the wheel
solution
we know that discharge = area × velocity .............1
here velocity = Cv√(2gh)
velocity = 0.98√(2×9.81×91.5) = 41.52 m/s
and area =
so from equation 1
0.04 = × 41.52
d = 0.00123 m = 1.23 mm
we know bucket speed to jet speed = 0.46
so bucket speed u = 0.46 v
bucket speed u = 0.46 × 41.52 = 19.1 m/s
and bucket speed =
so 19.1 =
so D = 0.506 m = 506.62 mm
so ratio is
ratio = 412
and
we know efficiency =
0.80 × ρQgh = output power
power output = 0.80 ×1000×0.04×9.81×91.5
power output P = 28.72 kW
so
speed of wheel is
speed of wheel =
speed of wheel =
speed of wheel = 13.63

Explanation:
The multiplicity of a root of a polynomial equation is the number of times the root repeats.
Let be the root of
, then;
has a multiplicity of 1.
has a multiplicity of 2.
has a multiplicity of 3.
has a multiplicity of m, where m is a positive integer.
We were given the root .
If
Then the multiplicity of the root is 1.
If
Then the multiplicity of the root is 4.
Since the polynomial function or equation is not given in the question, we cannot determine the multiplicity of this root.
But I hope with this explanation, you can refer to the original(complete) question and choose the correct answer.
