Your at the entrance of the mined-out area of an underground mine. Assuming a mine resistance factor of 0.3 N s2/m8 in this part of the mine, calculate the minimum static pressure required by a fan located at the entrance of the mined-out area to deliver a total of 5000 m3 to the inactive headings in this area of the mine. i) Calculate the minimum total pressure. Units are in Pascals (calculate to 2 d.p)
