4.2 The following are operating conditions for a steam generator: Coal analysis: carbon 61%, hydrogen 4%, oxygen 3%, nitrogen 2%, sulphur 1%, moisture 4% and ash 25%. Dry flue gas analysis: CO2 12%, CO 1.3%, 02 7% and N2 79.5%, unburnt carbon 0%. Exhaust temperature is 170 °C, Ambient air temperature is 30 °C, average specific heat of dry flue gas cp is 1.05 kJ/kg.K. Determine: 4.2.1 the amount of dry flue gas produced per kg fuel 4.2.2 the dry exhaust loss 4.2.3 energy loss due to incomplete combustion

I am attaching both questions for 4 and 5 with the question in the image. thank you. NOTE : So the last person answered this question WITHOUT refencing the answer for whether question 4 or 5 answeres were given, so i am asking for question 5(or the answer for the question that was NOT solved because it was not referenced.) These were the following answers given to me from the last person on bartleby who answered my question without referencing whether it was the answer for question 4 or 5. 1 pass 2 fail 3 fail 4 pass

Question 2 You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial weight bearing activities. Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the yield stress for the…
