Answer:
Throat diameter =28.60 mm
Explanation:
Bore diameter ⇒
Manometric deflection x=235 mm
Flow rate Q=240 Lt/min⇒ Q=.004
Coefficient of discharge =0.8
We know that discharge through venturi meter
=13.6 for Hg and
=1 for water.
h=2.961 m
Now by putting the all value in
⇒=28.60 mm
So throat diameter =28.60 mm
Answer:
Explanation:
Given that
R=8 ft
Width= 10 ft
We know that hydro statics force given as
F=ρ g A X
ρ is the density of fluid
A projected area on vertical plane
X is distance of center mass of projected plane from free surface of water.
Here
X=8/2 ⇒X=4 ft
A=8 x 10=80
So now putting the values
F=ρ g A X
F=62.4(32.14)(80)(4)
Answer:
minimum electric power consumption of the fan motor is 0.1437 Btu/s
Explanation:
given data
area = 3 ft by 3 ft
air density = 0.075 lbm/ft³
to find out
minimum electric power consumption of the fan motor
solution
we know that energy balance equation that is express as
E in - E out = ......................1
and at steady state = 0
so we can say from equation 1
E in = E out
so
minimum power required is
E in = W = m =
put here value
E in =
E in =
E in = 0.1437 Btu/s
minimum electric power consumption of the fan motor is 0.1437 Btu/s
