Answer:
Q = 86.38 gpm
Explanation:
pressure in house = 135 psig
1 psig = 6894.76 pa
= 135 × 6894.76 pa = 930792 pa
P = ρ g h
h = 94.88 m
velocity at the exit of nozzle
discharge (Q) = Av
=
=
Q = 86.38 gpm
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:
Minimum area of rectangle = 24 cm²
Explanation:
Given:
Length of rectangle = 6 cm
Width of rectangle = 4 cm
Find:
Minimum area of rectangle
Computation:
Area of rectangle = Length of rectangle x Width of rectangle
Minimum area of rectangle = Length of rectangle x Width of rectangle
Minimum area of rectangle = 6 x 4
Minimum area of rectangle = 24 cm²
