Question 10 2 pts Why do trees need water to reach their leaves? Water is important for photosynthesis because it replenishes electrons to the electron transport chain in the light reactions. Water is important for cellular respiration because it accepts the electron in the electron transport chain. Water is important because it is a major product of photosynthesis. Water is important because it is consumed during the Calvin Cycle. 2 pts Question 11

Question 3 2.5 pts Water enters a conically shaped tank 3 m high and 0.5 m in diameter, through a pipe with an internal diameter of 5 inches. Heat is added to the system via an electrical element and the water exits the conical tank at the bottom at a higher temperature than it entered. If the conical tank is the control volume, the size of the control volume is: O 2 m3 8 m3 Impossible to calculate None of...

3) Adding heat at constant volume: You have a 10 L (10 -2 m 3 ) fixed volume container that initially contains 1 kg of water. The water exists in both vapor and liquid phases, and is at an initial temperature of 180 C. Heat is then added until the final temperature of the water in the container is 250 C. This problem involves calculating the amount of heat that is added to achieve this final state. I will roughly...

Question 4 10 pts A source moving through the water at 10.0 m/s generates water waves with a frequency of 5.0 Hz. The speed of these water waves is 20.0 m/s. The source approaches an observer who is at rest in the water. a What is the wavelength of the water waves when it just leaves the source? b. What wavelength would be measured for these waves by the stationary observer? What is the frequency of the water waves measured...

2. (10 pts) A municipality is designing an open storm drain channel in the form of an in verted trapezoid. It has a width of L at its base, is symmetric about the vertical, and its sides are at an angle θ to the horizontal (Fig. 2). Assuming the Manning formula, i.e grating for pedestrians where O-v3o./n is fired for this prob- lem (because material and slope are already known), determine Q as a function of Co, L, 0, and...

3. (10 points) Assume that a container of liquid purified water at P=1 bar can be superheated to reach T=376 K without boiling. A nucleation event then takes place and the water quickly reaches equilibrium. Calculate the percentage volume increase upon the nucleation, i.e. how does the volume of the remaining liquid and produced vapor compare to the volume of the liquid prior to the nucleation. Use the heat capacity at constant pressure value Cp=4.215J/(g K). The enthalpy change on...
