Homework Answers
a)
In piezometric test head loss is nothing but the difference of available heads at two points.
Hence in this case,
Head loss = h2 - h1
= 4 - 1.5
= 2.5 ft
b)
Flow always occurs from high head to low lead.
In the given case, head at point 2 is 4ft and that at point 1 is 1.5ft i.e., point 2 is having higher head. Hence flow direction is from point 2 to point 1
