Explanation:
<h3>VELOCITY RATIO :- The ratio of a distance through which any part of a machine moves to that which the driving part moves during the same time.</h3>
To answer your question it is true
Answer:
56.6 m/s
Explanation:
The velocity of an object accelerating at constant acceleration is given by the following SUVAT equation
where
u is the initial velocity
a is the acceleration
t is the time
For the object in the problem,
u = 0 since it starts from rest
is the acceleration
Substituting t = 12.3 s, we find the velocity at that time:
Answer:
The Reynolds numbers for flow in the fire hose.
Explanation:
Given that,
Diameter = 6.40 cm
Rate of flow = 40.0 L/s
Pressure
We need to calculate the Reynolds numbers for flow in the fire hose
Using formula of rate of flow
Where, Q = rate of flow
A = area of cross section
Put the value into the formula
We need to calculate the Reynolds number
Using formula of the Reynolds number
Where, =viscosity of fluid
=density of fluid
Put the value into the formula
Hence, The Reynolds numbers for flow in the fire hose.
