Minor head losses in pipes When velocity of flowing liquid changes (either in magnitude or in direction) then there is minor losses in head (Energy) which is called minor head losses in pipes . In case of long pipes these losses are usually quite small as compared with the loss of energy due to friction and hence these are termed as 'Minor head losses' which may even be neglected without serious error, however, in short pipes these losses may sometimes outweigh the friction loss. In addition, minor head losses are negligible when they include only 5% or less of the friction head loss, So, it can be concluded that minor head losses are significant for short pipes only. Ad: https://happyshirtsnp.com/ Types of minor head losses There are different causes of minor head losses; some of them are discussed below. i)Head losses due to sudden expansion of pipe: Let us assume that liquid is flowing through the pipe from section 1 to section 2 where there occur
