Hi please can you help.

I need to calculate the flow rate of water in litres per seconds.

I have 50000 litres (50 m3) of water in a tank at a height of 11.5 metres.
The water will be flowing out of the tank down a ramp of 30 metres.
The angle of the ramp from the floor to the tank will be 22 degrees.

From this can you work out the flow rate in Litres per second.

Also can you tell me if the rate would double if I doubled the amount of water?

Also if possible can you explain how to work it out in case I need to change the figures.

Many Thanks

Richard Brooks

From: Dramane Yadi - [email protected]
From: Mr. Dramane YadiAbidjan Cote D'Ivoire West - Africa

Dear Richard Brooks,

I am Mr. Dramane Yadi, I work in the Accounts/ Operations Department of a Prime banks here in Abidjan Cote D'Ivoire. I actually have an urgent and very confidential business proposal for you. I got your contact from Internet and decided to contact you immediately.

On January 10th 1994, An American Oil Consultant/ Contractor with the Societe Ivoirienne De Raffinage (SIR), Mr. George Norman Wesley, made a number time (fixed) deposits valued at US$8,750,000 (Eight Million, Seven Hundred & Fifty Thousand United States Dollars). On investigation, it was discovered that Mr. Wesley died along with his family in a plane crash. On further investigation, I discovered that Mr. George Norman Wesley did not leave a WILL and all attempts to trace his Next of Kin proved abortive. I therefore made further investigation and discovered that Mr. Wesley did not declare any Next of Kin in all his official documents, including his Bank Deposit paper work. This sum of US$8,750,000 is still floating in the Bank and the interest is being rolled over with the principal sum at the end of each year. For the past 5 to 6 years now, no one has ever come forward to claim the fund.
According to the Ivoireinne Laws, at the expiration of 7 (seven) years, the money will revert to the ownership of the Ivoireinne Government if nobody applies to claim the funds. That is what gave way to this deal.
Consequently, my proposal is that I will like you as a foreigner to stand in as the Next of Kin to Mr. George Norman Wesley so that the fruits of this old man's labour will not get into the hands of some government officials.
To facilitate the transaction therefore:

1. I would like you to provide me with a viable account details where this fund could be safely transferred into as Next of Kin of the former depositor.

2. We do not anticipate any risk/problem whatsoever, as all the loopholes has been taken care of and there is no risk involved in this deal. All the Computer work for this transaction will be done by me, including your name as the new Beneficiary of this fund.

You will be entitled to 30% of the total amount as your commission after the transaction. If you are interested and capableof handling this deal, please write. On receipt of your response, I shall then provide you with more details on how to go about it.

Please note that this is very confidential. And as I am still a staff with the bank here. I would not like to be known or mentioned as having knowledge of the deal but I will be giving you inside information on what to do.

Awaiting your urgent reply. Do not forget to include your direct telephone and fax numbers for further communication.

Faithfully Yours,

Mr. Dramane Yadi

this is kinda vague.... is the tank 11.5 meters tall or 11.5m off the ground?

the length of the ramp and angle that its at (and height off the ground) is irrelevant, all you need to know are dimensions of the tank (specifically depth of the water) + size of hole

assuming gravity is constant??

Ok
The tank holds 50000 litres (50m3) of water.
So that means its 50m x50m x 50m.....(i think)

no

cube route 50,000 (if the tank is a cube)

Surely this can't be done with the information given. 30 meters what? Long, surely that makes no difference, so wide? How big is the hole letting the water out?

u need to know the pressure

cos if the tank was wide then there would be less, if it was narrow there would be more pressure

i think

6 arbituary units.

Is it an open top tank, so that the pressure is atmospheric?
