The sensor case must not permit any ingress of dust or water so think the LVDT is the best option here...

Homework Statement , [/B]I have to recommend a linear portion control sensor, that can be used in an explosive environment. Unsafe electrical contacts should be avoided and the case must not permit any dust or water.Homework EquationsThe Attempt at a Solution . [/B]My thoughts are either a LVDT...

Don't have a textbook Chet only course notes they have provided. If you could recommend a good book or relevant PDF files I can find online feel free...

Chet trust me this was a last resort. I have spent 3 days 12 hour days reading my course work and this isn't covered at all hence why I need the help. The tutor is asking if I have ever used the energy balance equation but I have no idea what this even looks like

Have you an equation for that so I can look through the course work...

yeah Chet I know about those. Its actually from a heat transfer and combustion task I have been set...

afraid not Chet this is how I'am finding this question extremely difficult. I would imagine once you have a handle on what you stated the question is relatively simple?

Yes Jobrag it was a typo should have been 200 deg C

Homework Statement Dry saturated steam at a temperature of 180ºC is to be produced in a fire tube boiler from cooling of 50000 kg/h of flue gases from a pressurised combustion process. The gases enter the tubes of the boiler at 1500ºC and leave at 100ºC. The feed water is externally preheated...

your 100% correct Chet I have got the correct answer my post was in haste

Anyone get any further with this question? Its really becoming a bug bear of mine I can't seem to get it any further along...

I would gladly take a pass for this now just get it complete and move onto something else. I sent you a private message if you can help I will send a private message with my email

The mass is correct though I know that much but I can't for the life of me get the positions worked out. This set of questions are especially hard! Take it you still have to complete this then?

I am working through this question also and was looking to confirm that in post #7 that the answer is the mass is 1.62kg and a=0.25m b=0.75m. Is that correct? If so why doesn't a and b add up to the length of the shaft at 2m? Very confused!

CWatters or MorgansRocks do you have the velocity diagrams and acceleration diagrams for this question? Its thrown me a little since its a set up I am unfamiliar with.
