I've got a project that needs a refrigerant cooling circuit. I am going to need to size the various components of a refrigerant loop to cope with the heat rejection requirements.
Could anybody please recommend some reading/study material, ideally that gives an example of specifying a full...
Thank you very much, that has fixed it.
I'm not sure where (pi·m -e)/d comes from though, that table 9 in DIN5480-15 definitely states (pi·m-e)·d
I'm not sure what the physical meaning of BETA is, but had imagined it was suppose to be around 30 (the pressure angle) and suspected that was the...
Not a programming problem. The program runs fine, it's just a representation of the maths (as it's an iterative problem).
Using positive values for d I get a positive value of Factor B:
Factor B = (pi*m -e)*d = (pi* 3 - 6.305) * 114 = 355.6547
invBETA = 355.7112 (or 355.8175 if I swap the...
Thanks, that helps highlight whereabouts in the calculation I've gone wrong.
I was calculating Beta with an implementation of the basic program in the standard written in VBA. I've actually iterated this by hand for the first 6 or so iterations to double check I'm getting the expected results...
I've been working through the spline design example given in DIN5480-1 (120 x 3 x 38 x 9H 8f) but using the calculations given in Table 9 of 5480-15 I am struggling to match the measurement over balls values given in DIN5480-1 Fig6.
I'm assuming that values for e/s should be substituted for...
I want to add some logic to a model so that part of a sketch has either a line or an arc drawn dependent on the value of a parameter. So if 'Parameter' > 1 then draw as a line else draw as an arc. Either the arc or line need a tangency condition at one end and a coincident condition at the...
