The land we can assume it's flat. The water comes from a Tank We are just going to use a standard pump. The trees are actually for a cement factory. We are only using the trees to hold the dust from going to our neighbors. So we are not really worried about some trees getting more water than the...

We are planning to plant 500 trees, and we want to water it, but we are not sure how to calculate the suitable pump for it, and the holes diameters that we will pinch for each tree (500 holes). The system will include two elbows, and the distance of the pipes are all included in the below link...

So I did a project about a year ago and I can't remember one of the things I wrote in this equation. The equation apparently I got it from NASA's website. https://www.grc.nasa.gov/www/k-12/airplane/dragco.html This is my equation CD = FL/ (0.5 * Air viscosity * V^2 * Area) = 0.4These are the...

We want to increase the efficiency of our solar panels at home by decreasing their temperatures. Is there an equation that would help us calculate the distance between each fin and how many fins we should install? And an equation to calculate the suitable shape of fin to be using? And should...

I am making a small project at home for my solar panels. I have made a similar project when I was in school but I can't remember the equations. I want to attach an air compressor to a tube then install it on top of a solar panel, and pinch a few holes in it to clean the dust that accumulates...

I'm going to do it of course but I am not sure what equation I should be using I need a name for an equation so I can look it up and plug in the numbers

You mean the Solar panel will not produce enough energy to power the the compressor?

We are thinking about an air tank that should be filled up using the solar panel

I understand it's expensive. We are not going to buy it, I am simply going to draw it using Solidworks next to the solar panel. I am asking this question because if I choose one of the motors my professor will ask me "what type of calculations have you came up with, to choose this particular...

I am not sure we have the power to do that

Thank you all for your input. I just realized how little I know about weather. However, I need help calculating the motor power I need for the air to cover the whole solar and how many holes I need for the tube "I am going to attach a 35 in tube from one of the sides of the solar and has a...

The solar will be placed in the desert. Anyways, it's too late to try and do something else we have to work on this one.

"brushing mechanism" That was our first design using a stepper motor. However since the solar is going to be installed in a very dry area (No rain) a compressed air system seems to be more effective. We only want to blow the dirt out of the solar panel surface. Brushing mechanism would require...

I am making a self cooling & self cleaning solar. I have already finished the cooling part by attaching fins from the back of the solar. Now, I am going to clean the solar using compressed air system. I am going to attach a 35 in tube from one of the sides of the solar and has a diameter of...

water moves over a stationary horizontal flat plate of one-meter length. if velocity of water is 1 m/s, draw boundary layer and friction coefficient versus x for this plate. hint: start your curves from x=1cm.Professor asked us to do it in Matlab or Excel and I'm not sure I understand how to...
