Homework Help: Basic Steriliser Questions

  1. Oct 4, 2014 #1
    I'm currently in my first week of undergrad chemical engineering and was set these questions to answer, so any help or any pointers will be greatly appreciated. Thanks.

    a) 32000 kg/hr + 5000 kg/hr = 37000 kg/hr

    b ) (The question is meant to be 0.05kg) 37000 * 0.05 = 1850 kg/hr

    c) I'm not entirely sure what to do on this question, I'm assuming it has something to do with Q = mc(DeltaT) but i'm not 100% sure how I would apply this.

    d) I used a online calculator for this and obtained a value of 1.55 Mpa.

    e) I'm unsure on how to answer this question.

    f) I answered a shell and tube heat exchanger.

    Thanks for the post! Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    In (c) you can determine the flow rate vertically, and you are told it cools from 135° to 40°. The heat it loses goes into warming the horizontal flow from ambient to ???

    Determine ??? stating any assumptions you make.
