6. As shown in the figure, a hole is to be punched out of a plate having an ultimate shearing stress of 300 MPa. a. If the compressive stress in the punch is limited to 400 MPa, determine the maximum thickness of plate from which a hole 100 mm in diameter can be punched. b. If the plate is 10 mm thick, compute the smallest diameter whole which can be punched. Answer: t = 33.3 mm d = 30.0 mm

Problem: Consider fully-developed flow of water through a 24-cm diameter tube. The water comes in at 20°C and exits at 40°C. The surface temperature of the tube is uniform at 60°C. The water flow has a mass flow rate of 0.24 kg/s. What is the average convection coefficient of the water flow? Solution: We have T, = 60°C, Tmi = 20°C, Tmo = 40°C, So, the bulk-mean temperature is Tm = 30°C. The appropriate properties are: u = 7.98 × 10-4 kg/ms; k = 0.615…
