Thanks - but I don't think thin-walled would apply in this case ? Because of the dimensions wouldn't this be classified as a thick walled pressure vessel ?

Sorry typo - 100mm not m !

In theory I was thinking of using the formula for hoop stress (as hoop stress is the max stress rather than axial or radial) as this problem is a thick walled rather than thin walled pressure vessel. I do have the equations which are below. So I'm thinking that if I use 207Mpa as the value for...

Homework Statement I have a simple cylindrical pressure vessel with thickness 100m and inner radius 254mm,.the cylnder has flat head closed ends but these are thickness 30mm. I need to calculate the pressure that would cause the vessel to collapse given material properties E=207Gpa, poissons...

1. I am using FEA modelling for a vertical heated flat plate and I need to compare theoretical results with the FEA s/w modelling results. I have completed the model in FEA s/w and I'm getting different values for temperatures and because I can't work out theoretical values then I do not know...

I'm having a brain storm, If I have an 8 cylinder 4 stroke engine running at 4000 rpm over a 10 minute test and it consumes 4.4 Kg of fuel, then is the fuel mass flow rate as simple as the 4.4 Kg divided by the time to give me an answer on Kg/sec ? Thanks,

Hi. Thanks for the reply. This is where I get stuck as I can understand that when the steam enters at 450 it is superheated but at exit do I need to go back to the Saturated tables to obtain the temperature ?

Hi - this is what I have worked out so far : a) specific volume of steam at the turbine input and output : At state 1 call the values S1, H1 and at state 2 call the values S2, H2, From the Superheated steam tables I've looked up 300 degrees C and 1000 Kpa to give S1 (Sg) 7.125KJ/KG-K and H1...

1. Superheated Steam enters a turbine with a pressure of 10 bar and a temp of 300 degrees celsius, and exits with a pressure of 0.046 bar. As the steam flows through the turbine it undergoes adiabatic expansion according to the law pv to the power 1.131 = constant From Steam tables I have to...
