Having trouble using the bernoulli equation to work out the dynamic head for this experiment.
the equation I am using is as follows:
P1/ρg+(v1^2)/2g+z1=P2/ρg+(v2^2)/2g+z2
Where:
P= static pressure
v = fluid velocity
z = vertical elevation of fluid so z1 = z2 for horizontal tube
so equation is now:
P1/ρg+(v1^2)/2g=P2/ρg+(v2^2)/2g
now the measurements taken for static presure head (h), in meter which is related to P using this realtionship:
h = P/ρg
which allows the bernoulli equation to be rewritten as:
h1+(v1^2)/2g=h2+(v2^2)/2g
now i am having trouble rearanging this part of the equation to work out the the dynamic head for the experiment
