You are considering adding a water-based thermal store work in combination with the heat pump. What volume of store, in m³, would be required to be able switch off the heat pump for 2.5 hrs during heating periods? Assume the heat pump produces a constant 7 kW of heat, and that the store can be heated by 22°C. You may ignore storage and pipework heat losses.

You have been tasked with designing a set of gears made from a material with a Brinell hardness (Hg) of 201 MPa. Previously your company has produced gears with a commercially polished surface finish, but your boss is interested in how much the bending strength would be decreased if a machined surface was used instead, with all other factors kept constant. Considering the surface factor figure and the AGMA equation for bending strength presented below, approximately what percentage decrease in bending strength (S,) would we expect to see changing from a commercial polished finish to machined surfaces? Hardness (Hp) 120 160 200 240 280 320 360 400 440 480 520 1.0 `Mirror-polished 0.9 Fine-ground or commercially polished 0.8 - Machined or cold-drawn 0.7 0.6 0.5 Hot-rolled 0.4 0.3 As forged 0.2 Corroded in tap water 0.1 Corroded in salt water 60 80 100 120 140 160 180 200 220 240 260 Tensile strength S, (ksi) St Sn = S'nCskrk¢kms O 28% O 20% O 23% O 7% Surface factor C,

would it be difficult to use the machining processes that you havelearnt in this course on rubberlike materials? Provide details explanation on youropinion with good justification, taking into account the differences in term of themechanical, physical and thermal properties of this material as compared to metalDiscuss also any dilliculties that may be encountered in producing the desiredshapes and dimensional accuracies in machining rubberlike materials.
Consider the solid model design of piston picture (a). You have been assigned a task to manufacturethis piston based on the following methods:-a. Sand Castingb. Any other manufacturing method of your own choicec. Draw the complete engineering-based comparison between the adopted method of your ownchoice and sand casting for manufacturing the piston. Your comparison must include theeffectiveness of manufacturing method, stresses-based analysis in manufacturing methods,product finishing, time laps for completing the product, cost effectiveness of methods, laborcost analysis.d. How can you measure the surface roughness of the piston surface highlighted in picture (b),based on your previous knowledge of manufacturing processes? You must have to mention theequipment by which you will measure its roughness and write the accuracy level. You mustdraw a valid reason for selecting that equipment.Take the dimensions of piston at your own but take more realistically.
In your own words, state and justify your assumptions and comment on your working.Marks will be assigned for the quality of the presentation of the working and od the comments.

4. As shown in Figure 13, the top cover of the quenching furnace is lifted by a single acting cylinder, the load on the piston rod is 9kg, the known stroke of the top cover is 250mm, the piston area is 2cm, and the flow rate of the pump is 3L/min. Please calculate the following values: load pressure, forward stroke speed and time. Figure 13
