Question

A fluid flows through a pipe of constant circular cross-section diameter 1.1m with a mean velocity of 50cm/s. The mass flow rate of the flow through the pipe, given by the formula mass flow rate = (density) (mean velocity) (cross - sectional area), is measured to be 110 kg/s. Find the specific gravity, specific weight and specific volume of the fluid.

Answer 1

Step-by-step explanation:

Given

diameter(d)=1.1 m

mean velocity(u)=50 cm/s

mass flow rate(m)=110 kg/s

`A=0.950 m^2`

`m=\rho \cdot A\cdot u`

where
`\rho` =density of fluid

`110=\rho * 0.95* 0.5`

`\rho =231.46 kg/m^3`

Therefore specific gravity
`=(\rho )/(\rho _(water))`

`=(231.46)/(1000)=0.231`

Specific weight
`=\rho \cdot g=231.46* 9.81=2270.70 kg/m^2-s^2`

specific volume
`=(1)/(density)`

`=(1)/(231.46)=0.00432 m^3/kg`
