Kelvin Scale

Explanation:

As in Kelvin scale 0 is absolute zero temprature and in celcius scale it calculates  -273.15 'Celcius

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
