Q5. Two tanks A and B of surface areas 600 m2 and 300 m2 are connected by an orifice of 0.18 m2 in cross section. If the pressures in the tank A and B are 50 kpa and 35 kpa respectively, find the rate of flow in liters/sec at the instant when the water levels in the tank A is 2.5 m higher than that in the tank B. Take Cd for the orifice as 0.64.

Round off the following number to three significant figures:68.534s

71.7 is being marked wrong in McGraw Hill homework. I thought I had done it right with putting 86.03 but that is wrong also. I'm not trying to just find the answer, trying to find how to do this. Could there be a different number than 71.7? Where does the μk=0.20 come into the equation?

Hi, Could you please help with this question, if you need to take more credits then please feel free. showing working out if possible too please, Thank you

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…
