In a fed-batch culture, 200 g L-1 glucose solution is added at a flow rate of 50 L h-1. The initial culture volume (at quasi steady state) and the initial cell concentration are 600 L and 20 g L-1, respectively. The yield coefficient \[\left( {{Y_{\frac{X}{S}}}} \right)\] is 0.5 g cell mass-g substrate-1. The cell concentration (g L-1) at quasi steady state at t = 8 h is
