Open channels supported over tres-les, are generally known as
-
For least effect on the water table, the tube wells must be dug one in every
-
In plain sedimentation tanks under normal conditions, impurities are removed upto
-
Pick up the correct statement from the following :
-
For the same draw down in two observations wells at distances r1 and r2, the times after start of pumping are t1 and t2 hours respectively. The relation which holds good is
-
The valve fitted closely in a recess against an opening in a pipe, is generally
-
For calculation of economical diameter D of a pipe in metres for a discharge Q to be pumped in cumecs, Lea suggested the empirical formula
-
S1 and S2 are the draw downs in an observation well at times t1 and t2 after pumping. For discharge Q and coefficient of transmissibility T, the relationship, is
