How are streamlines and streamtubes used in flow?
Streamlines and Streamtubes A streamlineis a line that is tangential to the instantaneous velocity direction (velocity is a vector, and it has a magnitude and a direction). To visualize this in a flow, we could imagine the motion of a small marked element of fluid.
How is the discharge of a stream determined?
STREAM DISCHARGE MEASUREMENT (STREAM GAUGING) The discharge Qfrom creeks, small streams and rivers can be determined by a number of methods, four of which are discussed below. The determination of stream discharges is known as gauging and the choice of a particular method is one for the hydrologist or engineer.
Why is the cross sectional area of a streamtube constant?
From mass conservation, we see that for a steady, one-dimensional flow, the mass-flow rate is constant along a streamtube. In a constant density flow, therefore, the cross-sectional area of the streamtube gives information on the local velocity.
How to calculate steady state water tank discharge?
Units in Steady State Tank Discharge calculator: cm=centimeter, ft=foot, gal=U.S. gallon, m=meter, min=minute, s=second. Either the free discharge orifice or the submerged orifice can be modeled. The equations are the same for both cases.

What does it mean when water is coming out of your drain?
Water flowing from the backup drain pipe is an alert that a potentially damaging overflow condition is developing in the condensate drain pan. Any amount of water discharged from a backup drain pipe is too much and should prompt a call to a heating, ventilation and air conditioning contractor.
