4. You decide it's time to clean your pool since summer is quickly approaching. You
pool maintenance guide specifies that the chlorine, Cly, concentration of the pool should
be between 1ppm and 3ppm.
In order to determine if your pool is safe to swim in, you send a sample of pool water to
a chemist for analysis of the Cl, content. The chemist reports you need to determine how
much chlorine should be added to a 6000 gallon pool in order to obtain 2.4 ppm of
chlorine? (value 1; work 2)

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
