Can anyone show me how did they manage to get the 45.8 degree Celsius by interpolation? 7-102 A liquid delivery system is being designed such thatethylene glycol flows out of a hole in the bottom of a largetank, as in Fig. P7-100. The designers need to predict howlong it will take for the ethylene glycol to completely drain.Since it would be very expensive to run tests with a full-scaleprototype using ethylene glycol, they decide to build a one-quarter scale model for experimental testing, and they planto use water as their test liquid. The model is geometricallysimilar to the prototype (Fig. P7-102). (a) The temperatureof the ethylene glycol in the prototype tank is 60°C, at whichv = 4.75 × 10-6 m²/s. At what temperature should the waterin the model experiment be set in order to ensure completesimilarity between model and prototype? (b) The experimentis run with water at the proper temperature as calculated inpart (a). It takes 4.12 min to drain the model tank.

Consider the general form of the Reynolds transport theorem (RTT) given by dBsys / dt = d/dt ∫CV ρb dV +∫CS ρbV-› r·n-› dAwhere V-›r is the velocity of the fluid relative to the control surface. Let Bsys be the mass m of a closed system of fluid particles. We know that for a system, dm/dt = 0 since no mass can enter or leave the system by definition. Use the given equation to derive the equation of conservation of mass for a control volume.
