Ans. Given Sp. Gr. Of oil, S = 0.90                           H =  0.60 m Let Pa be the pressure intensity in pipe. Hence starting from the right  end.           Patm + sh = Pa/w                 Patm = 0                   Pa = SH                         =  0.90 * 0.60                        = 0.54 m of equivalent water column head. And Pa = 0.54 * w             = 0.54 * 9810               = 5297.4 N/m2          Pa = 5297.4 Pa
