Thanks! Its very informative!

[@AkashSharma-ij1ed]

Thankyou sir for this knowledgeable video

thank you for this. where did the 32 come from?

[@pharmaengineering]

Could you please share the timeline for that value?

[@waynewu7763]

@@pharmaengineering hello, its at 7:17-7:23. thanks!

[@pharmaengineering]

It's a formula to estimate the volume occupied by the reactors torispherical bottom dish i.e., (pi/32)*Di^3

How can we calculate Td24 value based on Dynamic DSC experiment?

[@pharmaengineering]

Take 2 data points from a significant exothern and use arrhenius law to establish the pre-exponential factor, activation energy and calculate Td24

Can we calculate tip speed of two different types of agitator small scale propeller and large anchor L/D is same but D/d not same

[@pharmaengineering]

No, if the process demands a specific mixing pattern, matching tip speed of two different impellers won't suffice

[@vrganesh9841]

Power per unit volume is the best method for two different impellers

[@pharmaengineering]

@@vrganesh9841 most of the cases if it's a homogeneous mixture there won't be any issue,
However if the operation demands a specific kind, then we have to
