    Hi, I have an assignment in my Physics class and I don't know where to start in solving these two problems. I just know I have to use Bernoulli's Equation and Torricelli's Theorem but I don't know how to apply it. :/ Can someone help me?

    1. What is the pressure change in methyl alcohol (SG = 0.791) flowing a 4.0 cm diameter pipe to a 1.5 cm diameter pipe if the velocity in the larger pipe is 0.40 m/s?

    2. Water flows steadily from an open tank. The elevation of point 1 is 10 m and the elevation of point 2 is 2 m. The cross-sectional area at point 2 is 0.0480 m^2 . The area of the tank is very large compared with the crosssectional area of the pipe. Find the gauge pressure at point 2

    Regrettably, forum policy forbids our doing homework problems, but we can offer help. How have you approached the problem so far? Do you understand the basis for Bernouilli's equation? How does the assumption of fluid incompressibility help you compute the flow velocity in the narrower pipe?
