need help with this! as soon as possible please (fluid flow in pipes)

here is my Q am facing a problem with i don't know how to start and i have to hand it in at 9 a.m

Q: In a chemical processing plant, a fluid (Benzene) must be delivered to point B with a pressure of 550 kPa. A pump is located at point A 21 m below point B, and the two points are connected by 240 m of plastic pipe (smooth pipe) having an inside diameter of 50 mm. If the volume flow rate is 110 L/min, calculate the required pressure at the outlet of the pump.
Take relative density of benzene  = 0.86 and its viscosity  = 4.2 x 10-4 Pa.s
