WebThe system curve is a plot of frictional losses (in head or pressure) for a system versus flow rate. You could generate a system curve by calculating friction losses at many flow rates and plotting the results. MEboost approximates the system curve by using one known condition of head loss and flow rate which we'll describe in more detail later. WebGeneral form.

WebThe head loss per unit length of straight pipe is proportional to the velocity squared , and is inversely proportional to the diameter D. This is given by Darcy_Weisbach equation. … WebTwo hard, steel carts collide head-on and then ricochet off each other in opposite directions on a frictionless surface (see Figure 8.10). Cart 1 has a mass of 0.350 kg and an initial velocity of 2 m/s. Cart 2 has a mass of 0.500 kg and an initial velocity of −0.500 m/s. After the collision, cart 1 recoils with a velocity of −4 m/s.

WebFlow vs pressure graph: ... From the above equation we easily can relate the relation is the volumetric flow rate is directly proportional to the velocity and the cross section area. The unit of the flow rate is cubic meter per second. ... If the head loss and pressure drop is given then we find volumetric flow rate or mass flow rate. 2. Webpressure head - p / γ; velocity head - v 2 / 2 g; elevation head - h; is constant along a stream line. This constant can be called the total head - H. The total head in a flow can be determined by measuring the stagnation …

WebThe velocity at one of these locations is solved for in terms of the difference of head between the two locations. Using the product of the upstream velocity and area results in discharge expressed as: where: Q a = discharge A 1 = upstream approach area A 2 = area of the throat or orifice opening h 1 = upstream head measurement h 2 = downstream ...
