Pharmaceutical Equipment's Capacity

How to Calculate the capacity of following Pharmaceutical Equipment’s:-

  1. F.B.D
  2. RMG
  3. Auto-Coater or Coating Pan.

Please elaborate in details with calculation.

To Determine capacity in kgs the density of a powder is measured n then multiplied by Liters.
Capacity iñterm of liters remain fix but in kgs vary depending upon density of powder.
For maximum mixing capacity usually 70-75%is taken and results r validated.
Minimum capacity is also determine by validating the results.
Capacity calculation
Determine capacity in term of liters,for this add measured volume water in RMG say it is 400 liters.find density of powder say it is 0.85.then
400×0.85=340kg
75%of it is
340×75/100=255kg
So full capacity is 340kg maxium mixing capacity is 255 kg.

How to determine density of powder?

Bulk density
d=m/v
add weighing amount of powder in measuring cylinder n note volume
e.g
200 gm powder n vol is 300 ml
d=200/300=0.66
