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

Answer:
The correct answer is B
Explanation:
On a multiple lane roadway that has a speed limit of 50 mph (that is 80.5kmh) or greater, a driver is legally required to signal his or her intention to change lanes at least 300 feet in advance of making the change.
This rule like other traffic rules is design to ensure the safety of other road users by preventing accidents which may stem from reckless driving.
Cheers!

Explanation:
The failure theory asserts that Material failure theory is the science of predicting the conditions under which solid materials fail under the action of external loads. The failure of a material is usually classified into brittle failure or ductile failure.
