Question

Please answer this problem FULLY with detail steps on how to slove. My professor normally has us answer these questions by hand, and for complex imformation to put the rest into Excel. So, the handworked steps and solutions would be greatly apprecited. Thank you!
For the following problems you must develop a diagram to show the situation, include a brief problem statement and clearly show the energy balance equations you are using (start from the appropriate form of the energy balance equation). Document your work, clearly indicate answers and comment on results. Problem 1 can be readily solved using the general energy accounting equation for a closed system. Problem 2 is best solved using the mechanical energy form of the equation for an open system. 2. water is syphoned from an aquarium with dimensions: length 40 crn, width 20 cm and height 40 cm. The tube is placed at the bottom of the water in the aquarium with the other end 1 meter below the bottom of the aquarium. The inside diameter of the tube is 0.5 cm. The initial water level is 2 cm below the top of the tank. Set this up in the spreadsheet so you can answer the following questions: a. Use the mechanical energy balance to obtain an expression for the mass flow rate of water removal as a function of water level. You should choose the surface of the water in the aquarium as the inlet to the system and the water leaving the tube as the outlet. What is the initial water rate in grams/s? What is the water rate when the level has dropped by to 10. cm? Estimate how long it will take to remove 3/4 of the water using the 2 rates above and assuming that the flow rate decreases linearly with time. Write a transient mass balance for the tank and set the rate of change of mass in the tank equal to the rate of water removal b. c. d. e. f. Set up a table to find water level as a function of time (numerical integration of transient mass balance) and compare with result from d.
