Consider Surface area of 3cm*3cm
The surface area of a horizontal wire line is
The surface area of a vertical wire line is
Horizon wire line and vertical wire line has each 73 and 400 in 3cm * 3cm. So the entire surface of plate is
The surface of plane stainless steel of 3cm * 3cm is 9cm2, so the surface of wire mesh is 710% of the surface of plane stainless steel.
