Answer:
L = 46.35 m
Explanation:
GIVEN DATA
\dot m = 0.25 kg/s
D = 40 mm
P_1 = 690 kPa
P_2 = 650 kPa
T_1 = 40° = 313 K
head loss equation
where
density is constant
head is same so,
curvature is constant so
neglecting minor losses
we know is given as
therefore
V = 25.90 m/s
for T = 40 Degree,
Re = 4.16*10^5 > 2300 therefore turbulent flow
for Re =4.16*10^5 , f = 0.0134
Therefore
L = 46.35 m
Answer:
