AI Thread Summary
To calculate water flow in custom-designed info desks, it's essential to determine the necessary slope for moderate flow, the total water volume required, and the suitability of the chosen pump. The water channel dimensions are 250 mm wide and 50 mm deep, with the “L” and “U” shaped bars measuring 1800 mm and 3800 mm, respectively. The pump selected has a delivery rate of 440 liters per hour and a delivery height of 1500 mm. Accurate calculations for slope and water volume are crucial for effective design and functionality. Assistance is needed to ensure the project meets performance expectations and job security.

Before I start off I wish to make it clear that I am by no means a rocket scientist. This is to say that I don’t have a clue in regards to how to go about this.

Issue at hand: My employer asked me to design 2 bars (info desks) that have a water channel running through the middle of them.

One of the desks take on the form of a “L” the other takes on the from of a “U”. The channel where the water is to flow through is 250 mm wide and 50 mm deep.

The length of the “L” form bar is 1800 mm x 1800 mm.
The length of the “U” form bar is 3800 mm x 3800 mm x 2800 mm.

I pump I plan on using has a delivery rate of 440 lph (liters per hour) with a delivery height of 1500 mm.

My questions:

a) What is the need a percentage of slope that is required to have the water move at moderate flow rate?
b) How much water is required?
c) Am I planning on using the right pump?

I am in dire need of assistance on this; my performance on this particular task will be evaluated and it could end up costing my job.

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
