A certain process requires 3.0 cfs of water to be delivered at a pressure of 30 psi. This water comes from a large-diameter supp
ly main in which the pressure remains at 60 psi. If the galvanized iron pipe connecting the two locations is 200 ft long and contains six threaded 90o elbows, determine the pipe diameter. Elevation differences are negligible.
1 answer:
Answer:
diameter of the pipe = 0.4932ft.
Explanation:
assuming d = 0.4932
Re = 3.16 x 10∧5/0.4932
= 6.4 x 10 ∧5
E/d = 0.0005/0.4932
= 0.0010 from moody chat t = 0.02
if 0.02 is beign substituted in equation 2 we will get the same required diameter of the pipe which is 0.4932ft.

Answer:
i)ω=3600 rad/s
ii)V=7059.44 m/s
iii)F=1245.8 N
Explanation:
i)
We know that angular speed given as
We know that for one revolution
θ=2π
Given that time t= 2 hr
So
ω=θ/t
ω=2π/2 = π rad/hr
ω=3600 rad/s
ii)
Average speed V
Where M is the mass of earth.
R is the distance
G is the constant.
Now by putting the values
V=7059.44 m/s
iii)
We know that centripetal fore given as
Here given that m= 200 kg
R= 8000 km
so now by putting the values
F=1245.8 N

Answer:
Amperes WB =<em> </em>
Explanation:
Amperes will flow back to the negative terminal because both the positive terminal and negative terminal contain the equivalent amount of current that will flow and it works in the starter motor.
