Answer:
Q=33.34 KW/m
Explanation:
Given that
D₁=0.42 m
A₁= π D₁ L
For unit length
A₁= π D₁ = 0.42 π m²
D₂=0.5 m
A₂= 0.5 π m²
ε₁= 1 ,ε₂= 0.55
T₁=950 K ,T₂ = 500 K
F₁₁+F₁₂= 1
F₁₁= 0
So, F₁₂= 1
Q=33.34 KW/m
Answer:
Q = 5.06 x 10⁻⁸ m³/s
Explanation:
Given:
v=0.00062 m² /s and ρ= 850 kg/m³
diameter = 8 mm
length of horizontal pipe = 40 m
Dynamic viscosity =
μ = ρv
=850 x 0.00062
= 0.527 kg/m·s
The pressure at the bottom of the tank is:
P₁,gauge = ρ g h = 850 x 9.8 x 4 = 33.32 kN/m²
The laminar flow rate through a horizontal pipe is:
Q = 5.06 x 10⁻⁸ m³/s
