I can't read what's written in front of the root symbol. Also, you need not plug in the value of g, look at the formula, g cancels out so omit it.Answer wrong
Why 0.03? The formula shows that its area in front of root symbol so it should ##\pi(0.015)^2##.0.03 is written in front of the root symbol.
Yes.With or without the g I will still can the same answer right?
I haven't calculated it but isn't that correct?Yea sorry missed out on that one..hehe.. I calculated as 0.27L/s. Did you get the answer?
Hmm...are you sure it is L/s, not mL/s?No answer is 0.064L/s
Sorry, the given answer is correct.The answer from post #1 0.064 L/s is written by my lecturer.
I already said you to omit g. Also, don't forget to multiply with coefficient of discharge.P1-9810(0.045)=Px
P2-9810(0.027)=Py
P1-P2=176.58
The question states that we have to find the water flow rate and 0.064 L/s is the actual flow rate. That's why I asked you to multiply with Cd.I thought the question is asking to find the theoretical flow rate so why we have to multiply Cd?
Explaining things is not my strong point, I thought you had some problem in arithmetic but I did not know that you haven't yet learned about calculating pressure at a depth. I would suggest you to ask your lecturer or wait for someone else to join.And can you explain to me how you get P1-P2 again?
