Liquid nitrogen at a temperature of - 240°f exists in a container, and both the liquid and vapor phases are present. the volume of the container is 3 cubic feet and the mass of nitrogen in the container has been determined as 44.5 ibm. what is the mass of liquid and the mass of vapor present in the container?

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
