WebMar 30, 2024 · Minor energy (head) loss occurs in the following cases-Loss of head due to sudden enlargement. Loss of head due to sudden contraction. Loss of head due to an obstruction in the pipe. Loss of head at the entrance to a pipe. Loss of head at the exit to a pipe. Loss of head due to bend in the pipe, and; Loss of head in various pipe fittings. WebL by the velocity head in the pipe segment of diameterd. The losses would be smaller if the expansion or contraction is gradual. When a pipe empties into a reservoir, all the kinetic energy in the fluid coming in is dissipated, so that you can treat this as a sudden expansion with the ratio . dD/0 = , yielding K L =1.

Head Loss Due to Sudden Contraction Problem - YouTube
WebPipe, Sudden Contraction. A sudden contraction (Figure 102) is characterized by head losses of the form: where is a head loss coefficient depending on the ratio , is the mass flow, g is the gravity acceleration and is the liquid density. and are the larger and smaller cross section, respectively. Notice that this formula is only valid for . WebThe local and minor head losses are caused by certain local features or disturbances like a change in size or shape of pipe which affects the velocity distribution and may result in eddy formations. The loss of head due to sudden contraction is equal to k c o n v 2 2 g. Value of constant k cont depends upon the ratio of the area of contraction.
