An aluminum measuring rod, which is correct at 5.0 C measures a certain distance as 88.42 cm at 35.0 C.Determine the error in measuring the distance due to the expansion of the rod. If this aluminum rod measures a length of steel as 88.42cm at 35.0 C, what is the correct length of the steel at 35 degrees C? The coefficient of linear expansion of aluminum is 22 x10^-6 C^-1.

Problem 3 (30): Steam at Too,1 340 °C flows in a cast iron pipe [k- 80 W/m.°C] whose inner and outer diameter are Di 6 cm and D2 -8 cm, respectively. The pipe is covered with a 4-cm thick glass wool...
Problem 3 (30): Steam at Too,1 340 °C flows in a cast iron pipe [k- 80 W/m.°C] whose inner and outer diameter are Di 6 cm and D2 -8 cm, respectively. The pipe is covered with a 4-cm thick glass wool insulation [k-0.05 W/ m°C]. Heat is lost to the surroundings at Too,2 - 21°C by natural convection and radiation, with a combined heat transfer coefficient of h- 18 W/m2 °C. Taking the heat transfer coefficient inside the pipe to...

Estimate H if the bottle is kept at 13 °C Wine bottles are never completely filled: a small volume of air is left in the glass bottle's cylindrically shaped neck (inner diameter d- 18.5 mm) to allow for wine's fairly large coefficient of thermal expansion. The distance H between the surface of the liquid contents and the bottom of the cork is called the "headspace height (Figure 1), and is typically H 1.5 cm for a 750-mL bottle filled at...
