Question: Water flows out of a 13.0mm-diameter sink faucet at 2.30m/s. At what distance below the faucet has the water stream narrowed to 10 mm diameter? What I've done is that... I found A_1 (faucet) to be 0.0001327m^2 and A_2 (bottom) to be 0.000314159m^2 So I did the whole A_1*v_1 = A_2*v_2 thing and found v_2 to be 0.915m/s Then I plugged it in, into Bernoulli's equation 1/2*rho*v_1^2 + rho*g*y_1 = 1/2*rho*v_2^2 + rho*g*y_2 (cancelling out the P_1 and P_2 because they.. cancel..) In which it is.. 0.5*1000*2.3^2 + 1000*9.8*y_1 = 0.5*1000*0,9715^2 + 1000*9.8*y_2 2645 + 9800*y_1 = 471.906 + 9800*y_2 9800*(y_1 - y_2) = -2174.094 So.. h = 0.222m Or so I thought... It's wrong, so what am I doing wrong? Is it my A_1 and A_2's, etc.???
