Informative thanks...so if height from bottom of sump to to top of land height is 1.5 mtrs at a distance of 35mtrs discharge point.... equals 5 mtrs head?
As a rough approximation yes. If there are any right angles etc this can add another m, so potentially 6. It is best to work our friction calculations, but in most instances this 'rule of thumb' can work well.

How to find out efficiency
What then is acceptable deviation from
midpoint of performance curve?
This depends on its usage and how long its run for.
