Determine Tbe Value Of Surface Roughness By C.L.A Method , R.M.S Method & Ten Point Height Method (Rz).

Extracted text: -) In the mcasurement of surface reughness, the height of 10 successive peaks and valleys over datum line were found to be 45, 30, 42, 25, 40,25, 35, 24, 35 and 18 pum. If these measurements were obtained on 10 mar Tength, determine the values of surface roughness by center line average ELA), root mean square (RMS) and ten point height (Rz) methods. +1h thickness?
