a boiler delivers 5400kg of steam per hour at a pressure of 750KN/m^2 and with a dryness fraction of 0.98.The feedwater of the boiler is at a temoerature of 41.5 °c . The coal used for firing the boiler haas a calorific value of 31000KJ/kg and is used at the rate of 670Kg/hr. Determine the thermal efficiency of the boiler and the equivalent evaporation F and A 100 °c .​

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)
