Dear sir,

I am now involved in modification of skirt calculations through my company. We are now at third trial of those modification check i want to ask u one query:-

in gusset plate calculation as per Brownell and young Method, new factor has been added after discussion with coade. formula is:-

P/(18000*Cnv_fac*l)+ CA

Please tell me that the factor "Cnv_fac" calls for what?

As i have to give the acceptance of these calculation for further communication please convey this to me.

Vishal,

The “Cnv_fac” is a short form of the conversion factor. The equation in the Brownell and Young is like this.

t = P/(18000*l)

on left you have thickness

on the right you have force / length.

if you do the dimensional analysis of this equation it will not work out, :p

Actually, the 18000 has units of psi and P is also in lbf. The 'l' is in inches. Only then will you get thickness on the left (in inches).

So, to make it work we have added a conversion factor. But, users still want to see a "18000" value when comparing with Brownell and Young, hence we added a separate conversion constant.

I hope this clarifies it.
