    • Q11:Problem 3: Tank Pressure Safety Your supervisor asks you to employ an old tank with a volume of 60 L, but he has concerns regarding its mechanical resistance to pressure for use in a modified process. The tank was originally rated for a maximum pressure of 36 bar (absolute). It has been established that for a safe operation (no risk of bursting), you are never to exceed half the maximum pressure specification of the tank. The plan is to use this tank to store a maximum of 1000 g of ethane at a maximum temperature of 450 K.

The heat from the fins induces an air flow (due to free convection) from the surroundings through the porous base and through the parallel plates, where they exit at the top. The surrounding temperature is constant at 80 °C. The base is square, with a width of 50 mm. Neglect heat transfer Air flow (via free convection) Fins Neglect heat transfer 50 mm Porous base Neglect heat transfer Figure 2: Free convection in between parallel plates. 40 mm Neglecting the heat transfer from the bottom of the base, and through the extreme left and right side of the fins, i.e., the only heat transfer is due to the convection in between the parallel plates (as shown in figure 2), calculate the minimum number of fins (plates) required if the required heat transfer rate is 18 W. [10 marks] You may assume that the thickness of the fins is negligible.See Answer
    • Q14:Question 3 A large horizontal brass plate is used to boil water at atmospheric pressure. What is the maximum permitted temperature of the plate so that it does not exceed the critical heat flux? [8 marks]See Answer
    • Q15:The chocolate peanut factory One worldwide-recognised brand in the field of agroindustry manufactures the industrial chocolate peanut snack W&W's in three steps. Initially, the peanuts are sieved in order to remove broken grains (B); then, the unbroken peanuts (P) are driven to the next unit where are first roasted and then covered with chocolate (C). Following, the third step consists of a crusting operation, where each piece is covered with a layer of a sugar (S) - water (W) mixture and then is dried. The scheme below shows the process. Qkg/h 0.590 kg P/kg 0.410 kg B/kg Sieving Qkg Bih Qkg P/h Qkg C/h Roasting & Coating Qkg/h w.kg C/kg w kg P/kg Qkg/h w.kg Cikg wkg P/kg Qkg/h 0.660 kg S/kg 0.340 kg W/kg Crusting Qkg W/h Qkg/h 0.290 kg C/kg 0.430 kg P/kg 0.280 kg S/kg The stream Qe is made of low quality pieces that cannot be commercialised so it keeps the same composition as the product sent to crusting unit. In average, there are 10 kg of satisfactorily coated peanuts per each kg of rejected peanuts. If the production of commercial W&W's is stated to be 1000.0 kg/h, find the mass flowrate and compositions of the rest of streams, this is, all feeds (Q₁, Q4 and Q₂) and exits (Q3, Q6, Qs and Q9). Assume that the process operates in steady state.See Answer
    • Q16:EML 4706 - Two water tanks, A and B, are 1.5km apart and you have been tasked with connecting the two reservoirs together so you can transfer water from one reservoir to another. The two reservoirs are open to atmosphere and the surface of the two reservoirs is at the same level. Your goal is to achieve a volumetric flow rate of at least 1 m³/s using a pump that outputs 20kW of power. Select a pipe material and size that would be appropriate for this application. You might have to research how to include power in a conservation of energy equation (covered in previous courses). Make any assumptions you feel are necessary. You do not need to consider minor losses if you choose not to. 1 PUMP BSee Answer
    • Q17:#Question 2 (20%) Construct the Cp vs. T graphs for hydrogen and ammonia, then compare the quantities of heat obtained in an isobaric process that operates between 300 and 600 K. Which gas has a larger quantity of heat? Comment on the difference. The Excel data template for H₂ is provided in "Q2-Cp_vs_T".See Answer
    • Q18:# Question 3 (20%) Compare the quantities of work obtained in a reversible isothermal (373 K) vs. isobaric (5 atm) process upon compression of O2 and CO2 from 1.0 to 0.1 L/mol. (-7.0 vs. 2.8 kJ/mol for O2 and 5.5 vs. 2.6 kJ/mol for CO2? Why more work with O2 than with CO2?See Answer
    • Q19:# Question 4 (30%) The reproduction of Figure 2D.10 for Nitrogen and Methane using both the NIST database and the VDW EOS is given in the PDF file "Q4_Figure2D-Graph". Comment on the degree of (dis?)agreement between the NIST and VDW EOS; and answer related questions on the each graph.See Answer
    • Q20:This is an individual assignment, and is worth 30 marks in total. You will need to answer all questions, and you need to bear in mind that in some instances you may need to use knowledge you have previously gained in other courses to solve these questions. Please submit your assigment online. Typed solutions are recommended, but clearly presented hand-written solutions will also be accepted. This assignment is due on 8th October at 11pm. If you submit your assignment late, you will be deducted 4 marks (i.e. 20%) per day that you are late. Question 1 Sheets of steel are typically made by rolling heated steel at high temperatures, resulting in a flat plate as shown in figure 1. The resulting hot flat plates are cooled by passing air at a fixed temperature of 295 K over the plate. The plate is 4 m long, and 1.2 m wide, and has a uniform temperature of 600 K. The velocity of the flow of air is 9.5 m/s. Air 4 m Figure 1: Flow of air over a flat plate. Assuming the sheets are oriented such that the air flow along the length of the plate (i.e., along the a direction, as denoted by the blue arrow), calculate: a) The local heat transfer coefficient at a distance 1 m from the leading edge of the plate (i.e. at x = 1 m) [4 marks] b) The average heat transfer coefficient over the entire plate [3 marks] c) The rate of heat transfer from the plate to the air. [1 mark] If the plate is re-oriented such that the flow of air now flows along the width of the plate (i.e. along the y direction, as denoted by the red arrow), calculate the rate of heat transfer from the plate to the air. [4 marks] In all cases above, you may neglect any heat transfer from the bottom of the plate.See Answer
