- A brass rod of length 50 cm and diameter 3.0 mm is joined to a steel rod of the same length and diameter. What is the change in length of the combined rod at 250 °C, if the original lengths are at 40.0 °C? Is there a ‘thermal stress’ developed at the junction ? The ends of the rod are free to expand (Co-efficient of linear expansion of brass = 2.0×10-5 K-1 steel =1.2×10-5 K-1arrow_forwardThe maximum flow rate of standard shower heads is about 3.5 gpm (13.3 L/min) and can be reduced to 2.75 gpm (10.5 L/min) by switching to low-flow shower heads that are equipped with flow controllers. Consider a family of four, with each person taking a 5-min shower every morning. City water at 15°C is heated to 55°C in an electric water heater and tempered to 42°C by cold water at the T-elbow of the shower before being routed to the shower heads. Assuming a constant specific heat of 4.18 kJ/kg·°C for water, determine (a) the ratio of the flow rates of the hot and cold water as they enter the T-elbow and (b) the amount of electricity that will be saved per year, in kWh, by replacing the standard shower heads by the low-flow ones.arrow_forwardA solid aluminum alloy [E=69 GPa; α=23.6×10−6/C∘] rod (1) is attached rigidly to a solid brass [E=115 GPa; α=18.7×10−6/C∘] rod (2), as shown in the figure. The compound rod is subjected to a tensile load of P=5.3 kN. The diameter of each rod is 11 mm. The rods lengths are L1=507 mm and L2=705 mm. Compute the change in temperature required to produce zero horizontal deflection at end C of the compound rod.arrow_forward

Steel's Young's modulus is Y = 1.1 × 1011 N/m2 and it's linear thermal expansion coefficient is α = 13 × 10-6 1/C. Randomized Variables Y = 1.1 × 1011 N/m2α = 13 × 10-6 1/C What is the volue of the stress, in pascals, that develops due to a rise of temprature to 21 C? Assuming the nails have a cross- sectional area of A= 10^-5 m^2 all of which is perpendicular to the stress force from the bar, what is the force acting on each due to that temperature rise?arrow_forwardAt a certain temperature, a simple pendulum has a period of 1.500 seconds.

If the temperature of the balls after quenching is 74°C, determine the rate at which heat needs to be removed from the water in order to keep its temperature constant at 50°C.arrow_forward
- Steam in a heating system flows through tubes whose outer diameter is 3 cm and whose walls are maintained at a temperature of 120°C. Circular aluminum alloy fins (k = 180 W/m·K) of outer diameter 6 cm and constant thickness t = 2 mm are attached to the tube. The space between the fins is 3 mm, and thus there are 200 fins per meter length of the tube. Heat is transferred to the surrounding air at 25°C, with a combined heat transfer coefficient of 60 W/m2·K. Determine the increase in heat transfer from the tube per meter of its length as a result of adding fins.arrow_forwardTwo concentric spheres of diameters 15 cm and 25 cm are separated by air at 1 atm pressure.
