Discharge is the flow rate of water passing a point on a stream at an instant … In physics and engineering, in particular fluid dynamics, the volumetric flow rate (also known as volume flow rate, or volume velocity) is the volume of fluid which passes per unit time; usually it is represented by the symbol Q (sometimes V̇). It contrasts with mass flow rate, which is the other main type of fluid flow rate. In most contexts a mention of rate of fluid flow is likely to refer to the volumetric r… WebFlow rate is basically defined as the quantity of a fluid flowing through a section of pipe or channel per unit time. Flow rate or discharge = Quantity of fluid flowing through a section of pipe/Time. For incompressible fluid, such as water, flow rate will be defined as the ratio of volume of fluid flowing through the section and time. batam wallpaper

WebThe mfgr's moving to higher flow rates for draining seems to me to be without benefit that could compensate for the downside. We have a new Samsung washer in our 1970 tract slab-on-grade house with a 2" ABS downtube, and have not had any overflows. (The outflow hose on the washer just barely fits inside the downtube.) WebSide channel spillways are typically used to discharge floods perpendicular to the general direction of flow by placing the control weir parallel to the upper portion of the discharge channel. ... If the flow rate per unit width is defined as q = Q/W, then the equation can be written as: q = Q/W = 3.1[H + v a 2 /2g] 3/2 = 3.1H e 3/2.
