Problem 1 •Through a refinery, fuel ethanol is flowing in a pipe at a velocity of 1 m/s and a pressure of 101300 Pa. The refinery needs the ethanol to be at a pressure of 2 atm (202600 Pa) on a lower level. How far must the pipe drop in height in order to achieve this pressure? Assume the velocity does not change. (Hint: Use the Bernoulli equation. The density of ethanol is 789 kg/m3 and gravity g is 9.8 m/s2.Pay attention to units!)
A gas with a velocity of 300 m/s is flowing through a horizontal pipe at a section where pressure is 6 x 104Nm2 (absolute) and temperature 40°C. The pipe changes in diameter and at this section the pressure is 9 x 104 N/m2. Find the velocity of the gas at this section if the flow of the gas is adiabatic. In computation take R = 287 J/kg°K and k=1.4

According to Torricelli´s theorem, the velocity of a fluid discharging through the hole of a reservoir is V=(2gh)^1/2, where h is the height of water above the hole, as shown in the figure. If the hole has a section Ao and the reservoir is cylindrical with a cross-section of area Ab>>Ao. Obtain a formula for the time it will take for the reservoir to completely empty if the initial height of the water is ho.
