WebExample: Chemical Protective Clothing (CPC) • Methylene chloride is a common ingredient of paint removers. Besides being an irritant, it also may be absorbed through skin. When using this paint remover, protective gloves should be worn. • If butyl rubber gloves (0.04 cm thick) are used, what is the diffusive flux of methylene chloride ... WebSep 25, 2024 · In the present chapter we shall need to make use of the error function erf a. This is the area under the gaussian curve from x = -a to x = + a: (4.1.2) erf a = 1 π ∫ − a + a e − x 2 d x. The area outside the limits x = ±a, which is the area under the two “tails” of the gaussian function, is sometimes called the complementary error function:
