1. The problem statement, all variables and given/known data I have been staring at these two problems for a LONG time now and keep getting stuck. Please help me, and try to explain so I can understand. ro = density p = pressure g = gravity h = height/elevation A = area v = velocity 1a) Use the principal of dimensional consistency, show that bernoulli's equation written as: P + (1/2)(ro)(v²) + (ro)gh = constant has the dimension of pressure. 1b) When it is written as: (ro)/[(ro)*g] + (v²)/(2g) + h = constant show that each term has the dimension of length. 2) Using equations a) A*v = A*v Left side both have subscript 1, right side have subscript 2. and the version of Bernoulli's equation: P/(ro) + (v²)/2 + gh = constant show that v(subscript 2) = sqrt((2*[p(sub1)-p(sub2)])/ (ro(1-[(A(sub2)/A(sub1))²]) Sorry if it's hard to read. I can't do this on my own and my roommate isn't here to tutor me like he usually does. 3. The attempt at a solution I don't even understand 1a and 1b. For 2, I can get as far as v[sub2] = [ro =(ro)gh - p]/[(ro)*(A(sub2)/A(sub1))²] and that's just by creating similar denominators for the second equation and substituting for v[sub2] with what i solved for the other v in the other equation. Help?
