I have attached the problem.(adsbygoogle = window.adsbygoogle || []).push({});

I know I need to apply the energy equation:

P1/(gamma1)+V1^2/(2*g)+Z1=P2/(gamma2)+V2^2/(2*g)+Z2+h_t+h_f-h_p+h_m

P=pressure

V=velocity

g=gravity

Z=elevation

h_t=head due to turbine

h_p=head due to pump

The above 2 are 0 since there's no turbine and pump in this problem

h_t=headloss

h_m=minor losses due to bends, valves, etc...

So I must solve for h_t.

This has me confused, isn't h_t=f*L*2*g/d?

where f=friction factor (obtained from mood's chart)

L=length

d=diameter

I don't understand why we are given K values if we don't use them, unless I can't apply the equation h_t=f*L*2*g/d?
