Good Afternoon Everyone,

Attached is copy of MathCAD worksheet on vertical vessel. The total height of the vessel is 72 ft. The skirt height is 18.333 ft. In the worksheet L is defined as the length of each section of the profile and z is the elevation from the base of the vessel. The function L has a negative number and z should sum up to 72 ft at the top of the vessel. Please I'm getting a strange number in L of -1.33 and z is reporting 73 ft and 72 ft. Would anybody who is good in programming help.

Regards,

Boyer

1. It will be better use for your problem not ceil but Ceil function. The Ceil function works with units - see the picture.

2. It will be good to have not only a program but the description!

In you program to determine n, you have assumed a 15' skert, but then you have set the h.skert to 18.33', so the calclation for n is too large.
