1. (3p) Write down the definition of the pressure in a form of an equation. (Check your lab handout!). Explain the meaning of each variable and specify required SI units for each variable.

1. (3p) Explain what a rate of flow is. Then write down an equation relating the rate of flow with cross-sectional area of a pipe and speed of fluid in the pipe. Specify SI units for each variable.

1. (4p) Write down the Bernoulli equation. Explain the meaning of each variable in it and specify SI units for each variable.

1. Solve this problem:Lane has two pipes connected to each other that transport water because he is very thirsty. The given density ofwateris =997kg/³. Theflow rateofwaterthroughthepipesisR=.008963522
