Homework Statement
is the solution given wrong ? from the bernoulli's equation , (PAPB) / ρg = hf + ZB  ZA , am i right ? P/s : the Velocity at A and B are the same , so they cancel each other ... but in the solution , the author gave (PAPB) / ρg = hf + ZA  ZB which is 18.27 +40 , IMO , it should be 18.2740 , am i right ?
