Document Summary
Bernouilli"s eqn: derived from the work-energy theorem, remember that huge ass equaion with three terms on either side. Along a streamline, the value of this funcion is constant. P1 and p2 are pressure in pascals work on the luid. 2 and same for v2 is density in velocity squared kineic energy. Pgh is density imes g imes height potenial energy: looked at three cases. Using fact that we have coninuity equaion: a1v1 = a2v2. V1 = a2 root {[2(p1 p2]/[p(a2 a1)]: previous note had a mistake and said p2 minus p1. Same velocity hydrostaics p1 p2 = pg(h2 h1) Check if luid is constant lowing in a tube to see if equaion of coninuity can be applied. Note: pressure in pascals not kpa or atm. 1 atm = 101. 7 kpa = 14. 7 p. s. i = 760 mm hg = 760 torr = 1 bar. With all this summary, solve all next week"s fucking.
