Effect of the concentration of the broths on the production scale. An industrial plant with a production volume V Prd (L), produces a number of batches per year, with a product concentration C (g/L). The global recovery is RG. It is requested: a) Write the expression for the annual production of the plant P A (kg / year) as a function of n, V Prd, C and RG. b) Write an expression to calculate the volume of production (scale) V Prd (L) to meet a demand of D (kg / year). c) Graph the effect of demand on the scale of production n= 20 batches / years, RG= 50% and values of C of 0.5, 1.0, 1.5, 2.0, 2.5 g / L.
