The cost of 20m' installed reactor column is 5000$ in 1970. The reactor is cylindrical with flat top and bottom and the height is 2m. The construction material of reactor is made from special alloy which resist corrosion. If the entire outer surface of the reactor is to be covered with an insulation block, estimate the present total cost for the reactor in 1979. The 1979 cost for the insulation block was 1.40$ per m? while the labor for installing the insulation was 3.00$ per m.
