2x^2+2x-3x-15
2x^2+(-1x)-15
1x^2-15 final answer
Choose the letter d because of the money
Explanation:
The frictional resistance of the various pipes are given by the
K value in the table which may be used with the formula
hf = KQ2
to relate the magnitude of head loss hf in the pipeline
to the volumetric flow rate, Q. Water is drawn at the constant flow
rates from the network at nodes C and D. The static heads
(elevation + pressure head) at nodes B, C and D are 100m, 65m
and 61m respectively above the local datum. Calculate the
discharges at C and D and the water level in reservoir A. (The
data has been added to the diagram to aid the solution)
Use no more than 3 iterations and 3 significant figures.
I’m pretty sure you are asking how to say happy birthday? So depending on the person it could be different. If it’s your friend you could give them a hug and say ahoy birthday and hand them a small gift. A relative you could call and send a gift card, or if it’s perhaps someone you like you could text them happy birthday or give/send them a little gift.
Hope that helped
