In common bubble cap distillation column design practice, riser area is approximately equal to (where, Aa = Annular passage area, and Sa = Slot area)
-
Heat transfer co-efficient, hG(Kcal/hr.m2 .°C) and mass velocity of air, G (kg/hr.m2 ) for air flow parallel to the surface in case of constant drying rate in batch drying is related as hG = 0.0176G0.8. But when the flow of air perpendicular to the surface is encountered, this equation changes to
-
In the agitators, the power required will be changed with the increase of diameter of agitator (D) as
-
Apex angle of conical heads used in the bottom heads of chemical process equipments is usually
-
Pressure drop due to pipe fittings can be estimated by the equation,
, where, Le = equivalent length of straight pipeline which will incur the same frictional loss as the fitting and D = diameter of the fitting. The value of 
(dimensionless) for 45° elbow and 180° close return bends would be respectively around -
A pressure vessel is said to be made of 'thick' shell, if the ratio of its diameter to wall thickness is
-
Rate of filtrate delivery is inversely proportional to the
-
Tube side heat transfer co-efficient for turbulent flow of liquid through tubes is proportional to
-
Circumferential (hoop) stress in a thin cylindrical vessel under internal pressure is __________ the longitudinal stress.
