Water (density = 62.4 lb/ft3, viscosity 1 cp) is pumped from a large reservoir on the floor at a rate of 80 gpm to the top of a small tower. the discharge point is 20 ft above the centerline of the pump. frictional and other (contraction, expansion, etc.) loses in suction and discharge lines amount to 1.5 ft head of liquid. if the pump develops only hp and the inside diameter of the pipe is 2 inches, the water height [ft] in the reservoir must be closest to: (c) 10.18 (d) 12.17 (c) 8.65 (d) 3.11 ie

Which of the following would be an accurate picture of the earth during the summer time of the northern hemisphere?

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
