The pump of a 500-m-long rising main develops a pressure head of 30 m. The main size is 0.3 m and carries a discharge of 0.15 m3 /s. A sluice valve is fitted in the main, and the main has a confusor outlet of size 0.2 m. Calculate terminal head.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
