Calculate the inner diameter of the steam tube between the boiler and the high pressure turbine if the average velocity of the steam(state 1) is 60 m/s.
given is the mass flow rate at 18 kg/s.
specific volume (v) is 0,036793 m^3/kg
velocity (v) given as 60 m/s
how do i calculate this ? ?

The inner diameter of the steam tube is 0.1185 m.

Explanation:

m = mass flow rate

= density of the liquid

V=specific volume =

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=?,

Area of the inner cross section =

d = 0.1185 m

The inner diameter of the steam tube is 0.1185 m.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
