I have two problems here involving Bernoulli's equation. In one, I set raw*g*h_2=0, and in the other, raw/2*v_1²=0. Now I'm wondering why? How do you approach problems like this? I think I'm lacking the understanding.
P connection = (1000 kg/m³ * 9.81 m/s² * 0.015 m³/60 s * 55 m/0.8)/0.6 P connection = 281 W
P connection = (rho * g * Q * h / h hydr ) / h electr (in watts) P connection = (1000 kg/m³ * 9.81 m/s² * 0.015 m³/60 s * 55 m/0.8)/0.6 P connection = 281 W I have now calculated the pump's performance, but how can I calculate how long it will…
Hi, I'm tasked with calculating the pipe diameters of several lines branching off a main line so that the specified flow rates are achieved. The available parameters are the zeta value of the heat exchangers, the length of the lines, the flow rates, possibly the flow velocity of the main line, and the number of…
Hi, once again I have a problem understanding this. I can understand everything so far, but the formula for v is Q/A like this, and why is the solution now calculating 23 × 4 hours again? And the second question is if I convert the diameter of the pipe into m it is 0.1 m…
Hello, How is it possible to determine the Reynolds number in a system I can adjust the volume flow so Q is given. but this is not included in the basic formula. P should be the density V should be the flow velocity d= pipe diameter I think n (eta) = dynamic viscosity Are these…
I have a problem where I don't really know the answers. I hope someone can help me out. The problem is a true-false problem. Thanks in advance! Someone is the production manager of a juice company and wants to reduce the pressure loss in one of the piping systems. What measures should be taken? Wrong…
