The grading and all other matters regarding this examination are governed by the general rules of the Sefako Makgatho Health Sciences University (SMU)

(9 points) Water at 1 atm is heated in a mechanically polished stainless-steel pan, with its surface is electrically heated to Ts = 110°C. The pan’s diameter is 20 cm. What is the power required to boil the water? Use the following properties for your calculations: Tsat = 100°C, liquid phase’s density = 957.9 kg/m3, vapor phase’s density = 0.5956 kg/m3, liquid phase’s specific heat = 4217 J/(kg×K), liquid phase’s dynamic viscosity = 279×10-6 Pa×s, liquid phase’s Prandtl number = 1.76, hfg = 2,257,000 J/kg, Surface tension = 0.0589 N/m.

(10 points) Liquid water at 37°C flows over a 0.5 cm diameter isothermal sphere (Ts = 22°C) at 0.2 m/s. What is the average convective heat transfer coefficient? Hint: (1) Density is the inverse of specific volume, (2) Subscripts f and g in property table correspond to the liquid and gas phases, respectively.

(10 points) Calculate the heat transfer coefficient of the window ONLY at the outside. The window has a square shape with dimensions of 1m by 1 m. Assume the air is stagnant on both sides. The inside ambient temperature (Ti) is 50 °C, while the outside ambient temperature (To) is -50 °C. Use the table shown below to evaluate the fluid’s properties. Slight rounding of the temperature values is allowed without performing linear interpolation.
