7–110 Write an article on forced convection cooling with air, helium, water, and a dielectric liquid. Discuss the advantages and disadvantages of each fluid in heat transfer. Explain the circumstances under which a certain fluid will be most suitable for the cooling job.
18. A 50/50 blend of engine coolant and water (by volume) is usually used in an automobile\'s engine cooling system. If your car\'s cooling system holds 6.20 gallons, what is the boiling point of the solution? Make the following assumptions in your calculation; at normal filling conditions, the densities of engine coolant and water are 1.11 g/mL and 0.998 g/mL respectively. Assume that the engine coolant is pure ethylene glycol (HOCH2CH2OH), which is non-ionizing and non-volatile, and that the pressure...

A Rankine cycle is shown below. Cooling (liquid) water removes heat from the cycle as shown in the figure. Recall that for a liquid/subcooled liquid/compressed liquid, you may make the following approximation: h(T,P) hr(T) Determine the thermal efficiency of the cycle as well as the mass flow rate of the cooling water as shown in the figure. Given Pg = 10MPa,T2 = 500°C, rn = 10 kg High P.Lo P Pa =700kPa Ts = 500°C Pa = 5kPa Condenser cw.out...
