Calculate the inner diameter of the steam tube between the boiler and the high pressure turbine if the average velocity of the s
stich3 [128]

Answer:

The inner diameter of the steam tube is 0.1185 m.

Explanation:

m=\rho \times A\times v=\frac{1}{V}\times A\times v

m = mass flow rate

\rho = density of the liquid

V=specific volume =\frac{1}{\rho }

v = velocity of the liquid

A = area of cross-section

Diameter of the cross-section = d = 2r

Given: m = 18 kg/s, v = 60 m/s,A=?, V = 0.036793 m^3/kg

18 kg/s=\frac{1}{0.036793 m^3/kg}\times A\times 60 m/s

A=0.0110379 m^2

Area of the inner cross section = \pi r^2=\pi \frac{d^2}{4}

\pi \frac{d^2}{4}=0.0110379 m^2

d = 0.1185 m

The inner diameter of the steam tube is 0.1185 m.
