Answer / sandeep challa

High pressure drop
cost of construction is also high

Answer / amol deshpande

In bubble cap distillation coloumn, the cap above the downcomer can be blown out from it's position under the effect of high pressure. High Pressure drop is main problem encountered in valve.

Answer / ajithkumar

in bubble cap distillation problems
1. high pressure drop
2. material cost
3. reflux ratio
4. purity

I would like to know how to size a partial combustion reactor processing methane and oxygen, as a function of the flowrate and of the pressure.

BIOPROCESS ENGINEERING - EXAMPLE 14.3 : The kinetic behavior of an enzyme could be described using Michalis - Menten equation : Vo = Vmax [S] / (Km + [S]). Derive this equation from [ES] = [E]total [S] / (Km + [S]), Vmax = Kcat [E]total, Vo = Kcat [ES].

Water flows through a pipe with circular cross sectional area at the rate of V / t = 80 L / s where V is the volume and t is time. Let Av = 80 L / s where A is cross sectional area and v is velocity of fluid. For point 1, the radius of the pipe is 16 cm. For point 2, the radius of the pipe is 8 cm. Find (a) the velocity at point 1; (b) the velocity at point 2; (c) the pressure at point 2 by using Bernoulli’s equation where P Rgy 0.5 RV = constant. P is the pressure, R = density of fluid, V = square of fluid’s velocity, g = gravitational constant of 9.81 N / kg and y = 2 m = difference of height at 2 points. The pressure of point 1 is 180 kPa.
