Answer:
Length = 129.55m, 129.55m
Explanation:
Given:
cp of water = 4180 J/kg·°C
Diameter, D = 2.5 cm
Temperature of water in = 17°C
Temperature of water out = 80°C
mass rate of water =1.8 kg/s.
Steam condensing at 120°C
Temperature at saturation = 120°C
hfg of steam at 120°C = 2203 kJ/kg
overall heat transfer coefficient of the heat exchanger = 700 W/m2 ·°C
U = 700 W/m2 ·°C
Since Temperature of steam is at saturation,
temperature of steam going in = temperature of steam out = 120°C
Energy balance:
Heat gained by water = Heat loss by steam
Let specific capacity of steam = 2010kJ/Kg .°C
Find attached the full solution to the question.
Answer:
a)
b)Mass in lb = 376.8 lb
Mass in slug = 11.71 slug
c)
d)
Explanation:
Given that
d= 2 ft
r= 1 ft
h= 3 ft
Density
a)
We know that volume V given as
b)
Mass = Density x volume
mass= 376.8 lb
We know that
1 lb = 0.031 slug
So 376.8 lb= 11.71 slug
Mass in lb = 376.8 lb
Mass in slug = 11.71 slug
c)
we know that specific volume(v) is the inverse of density.
d)
Specific weight(w) is the product of density and the gravity(g).
w= ρ X g
w = 40 x 31.9
