A coal mine operating in three shifts produces 400 tonnes of coal per day with a face OMS of 1.0 from panel A, and 200 tonnes of coal with face OMS of 1.0 from panel B. The panel A and panel B are in parallel with resistance 0.6 Ns^2\text{m}^8 and 0.5 Ns^2\text{m}^8, respectively. If the panels are supplied with minimum permissible quantity as per CMR 2018, the requisite regulator resistance to meet the conditions in Ns^2\text{m}^8 is \(\underline{\hspace{2cm}}\) (round off to 2 decimal places).
