If I need 500 ltr tank (cylindrical) how do I calculate H value and R value?

If you need to find out the height and radius of a cylindrical tank with the capacity of 500 liters, you can get them as followsVolume of any cylindrical tank = 3.14*r*r*hSay the height is thrice the radius of the tank and now the formula can be written as3.14*r*r*3*r= 3.14*3*r^3=500000 ccr^3 = 500000/(3.14*3)r^3 = 53073.147r = 33.148Now the radius of the tank that holds 500 liters is 33.148 cm and height is 112.74 cm.

Because there are two variables r and h, there's going to be infinite combinations of r and h which will yield V = 500000. But you can solve either for 'r' or 'h' algebraically. Firstly note that 500 litres = 500000 cm³ = VI chose to solve for 'h' here (so the dependent variable is h, and independent variable is r)h = 500000 / ( Pi * r² )Then choose any positive value of r, say r = 100, then h = 500000 / ( Pi * 100² ) = 15.9155 cmYou can plot a graph to show the combinations of r and h which yields V = 500000.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
