(a) A water tank is completely filled with liquid water at 60rc. The tank material is such that it can withstand tension caused by a volume expansion of 4%. Determine the maximum temperature rise allowed without jeopardizing safety. Take water coefficient expansion (B) as 5.22 x 10*1K at this temperature. (b) A weight, as shown in figure Qib-(a) has to move at constant velocity of 2 m's on an inelined surface with a coefficient of friction of 0.27. The width of the block is 20 cm. Determine the force (FI) that needs to be applied in the horizontal direction. By applying a thick oil film as shown in figure Qlb-b), the force required to push the block reduced by 45%.

2) Air is compressed by an adiabatic compressor from 95 kPa and 27°C to 600 kPa and 277°C. Assume variable specific heats and neglect the changes in kinetic and potential energies. a) Determine the isentropic efficiency of the compressor. b) Determine the exit temperature of air if the process were reversible.

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 B

11) 3 kg or steam initially at 375 kPa and 141.3°C is contained in a piston-cylinder with a diameter of 88 cm. A spring, that is attached to the piston cylinder and initially at equilibrium at a piston height of 160 cm from the bottom, has a spring constant of 128,450N/m. If the piston raises to double its initial height, find the heat input into the steam.

Refer to each section of the engine and explain the purpose of each section. e) Draw a Temperature (T) versus Entropy (s) diagram for a typical gas turbine. The diagram should show the processes for an actual gas turbine and should show the effect of real world losses where the compressor and turbine have an isentropic efficiency and pressure losses in the combustion chamber in an actual gas turbine.Explain each of the processes on the T-s diagram.

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.
