Crude oil 30 degree api at 15.6⁰ c with viscosity of 75 universal saybolt seconds is flowing through a 12" schedule 30 steel pipe at a rate of 1900 barrels per hour. the pipeline is 60 miles long with discharge at an elevation 1,500 feet above pump inlet. assume the pump has an efficiency of 70 percent. 1 barrel = 42 us gal and 1 uss=0.167 centipoise find: the brake horsepower of the pump.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
