Batch Definition and 37 Threads

I am working on a project on vacuum drying vegetables using IR heaters. Before winter batch time was around 3 to 4 hours now it has increased to 6 hours. Any logic behind this as though the temperature drops and RH also drop so why has the time increased?

I don't know much about batch, but what I want is to execute a command such as ping google.com -n 200 and store all 200 ping latency results to a variable. The default results (avg max min %lost) isn't enough for me to tell if I can do what I need to do. I would like to calculate the average...

Hello, I went through a problem in my reaction engineering textbook, and solved them correctly by basically mindlessly plugging into the equation, but now I wanted to get some help interpreting the results. So we had a reversible, elementary gas phase reaction that is isothermal and isobaric...

I have a set of results over time that show the volatility of a batch and trying to determine state at the latter end of the process whether a batch is stronger or getting weaker? B4 has outperformed all other batches and showing an increase in latter results which means it is slowing or...

hi everyone . i came across this interesting problem but am not able to figure it out . In a factory that packs food in cans , there is a report that in a particular batch of 400 cans by error a poisonous chemical has been packed instead of food item. Checking 400 cans would be a big loss but...

Refer to the attached image Overview The feed to V12 comes from distillation unit, where batch production rate is 16 Ton/day and at 220 degC. At first it is cooled to 160 degC in V12. Now this bulk is transferred from V12 to V18 using N2 gas pressure. All the transfer lines are jacketed...
