Answer:
<em>screw thrust = ML</em>
<em> </em>
Explanation:
thrust of a screw propeller is given by the equation = p
x
Re
where,
D is diameter
V is the fluid velocity
p is the fluid density
N is the angular speed of the screw in revolution per second
Re is the Reynolds number which is equal to puD/μ
where p is the fluid density
u is the fluid velocity, and
μ is the fluid viscosity = kg/m.s = M

<em>Reynolds number is dimensionless so it cancels out</em>
The dimensions of the variables are shown below in MLT
diameter is m = L
speed is in m/s = L
fluid density is in kg/
= M
N is in rad/s = L
=
If we substitute these dimensions in their respective places in the equation, we get
thrust = M



= M


<em>screw thrust = ML</em>
<em> </em>
This is the dimension for a force which indicates that thrust is a type of force

Answer:
Head loss=0.00366 ft
Explanation:
Given :Water flow rate Q=0.15 
= 6 inch=0.5 ft
=2 inch=0.1667 ft
As we know that Q=AV

So 

=0.687 ft/sec
We know that Head loss due to sudden contraction

If nothing is given then take K=0.5
So head loss
=0.00366 ft
So head loss=0.00366 ft
