WebJul 30, 2024 · Volume = 4/3*π*r^3 + π*r^2*h = 2 Surface area = 4π*r^2 + 2πrh First, you equate h in terms of r using the formula for volume: Then, you substitute the expression for h in the formula for the surface area (SA): Then, you differentiate SA in terms of r and equate it to zero to find the value of r in order to get the maximum SA. WebA more appropriate parameter for measuring efficiency is the height equivalent to a theoretical plate (or plate height), HETP (or h ), which is L / N, L being the length of the column. Efficient columns have small h values ( …
