Answer:
rate of heat transfer = 9085708.80 W
Explanation:
Given:
Inside diameter, D = 5.1 cm
= 5.1 x
m
Average velocity, V = 7 m/s
Mean temperature, T = (66+38) /2
= 52°C
Therefore kinematic viscosity at 52°C is ν = 0.104 X
/ s
Prandtl no., Pr = 0.021
We know Renold No. is
Re = 
Re = 
= 3.432 X 
Therefore the flow is turbulent.
Since the flow is turbulent and the ratio of L/D is greater than 60 we can use Dittua-Boelter equation.
Nu = 0.023
.
= 0.023 x
x 
= 1221.52
Since Nu = 
h = 
= 
= 225143.3
Therefore rate of heat transfer, q = h.A(T-
q= 225143.3 x 2πrh ( 66-38)
= 225143.3 X 2π X 
= 9085708.80 W
Answer:
it is to warn you about something like a dead end, or maybe where you should slow down because there might be people crossing ahead.
Explanation:
look at the signs i provided, all of them warn you about something.
Ex: railroad tracks, there might be a train passing, a winding road, so you don't go off road and crash, etc.
