Calculate the diameter of a 2.27 cm long tungsten filament in a lightbulb if its resistance is 0.319 Ω. (The resistivity of tungsten is 5.60×10-8 Ωm.) This is an easy question but I keep getting it wrong, so I am confused please help. Maybe I am using the incorrect units.
1.2. Find the conduction thermal resistance of a 1 m long hollow Teflon pipe with internal diameter of 10 cm and external diameter of 12 cm. You can assume the temperature of this tube is 300 K.
A concrete column is 72 cm long and 29 cm in diameter. High quality has a compressive elastic (Young's) modulus of 30 GPa. What is its change in length if the column is loaded with 45000 kg?
Using Poisuille’s Law, calculate the flow rate in an artery of diameter 0.8 cm, length of 4 cm, with the coefficient of blood viscosity is 4*10-3 Pa-s at normal blood pressure of 120 mm-Hg. (6 points) How does this flow rate change upon a 20% occlusion of the artery? (4 points) What is usually the compensation process to hold the flow rate steady? (2 points)
