Chapter 3, Problem 70QAP

I need help with the following case

2. Jojoba oil is flowing through a ¾-nom stainless steel pipe at a flow rate of 1,850 lbm/h. After the velocity profile in the pipe is fully developed, the oil enters a heater, as shown in Figure P5.7. The length of the heater section is 5 ft. The properties of the jojoba oil at the average temperature in the heater section are given in Table P5.7. Determine the convective heat transfer coefficient inside the heater section of the pipe. ¾ nom stainless steel pipe Heater section L=5ft Fig. P5.7 TABLE P5.7 Thermophysical Properties of Jojoba Oil at the Average Temperature in the Heater P (lbm/ft³) 68.671 (Btu/lbm-R) 0.30339 μ (lbm/ft-s) 0.012095 k (Btu/h-ft-°F) 0.077424

1. Water is flowing inside of a 3-std type K copper tube at a flow rate of 1.2 kg/s. The average temperature of the water is 50°C. Cold, dry air at a temperature of 5°C and atmospheric pressure flows outside of the tube in cross flow with a velocity of 85 m/s. Determine the UA product for this tube under clean conditions.

Determine the following for the beam with unknown loading, using the Shear and Bending Diagrams provided in the figures on the right: a. The maximum shear stress experienced by the beam. b. The maximum flexural stress experienced by the beam (Indicate if this is tensile or compressive flexural stress) c. The loading diagram (Indicate the magnitudes of the loading/s. The loads are acting along the plane of symmetry of the section) 20 80 20 十十 SHEAR DIAGRAM x=577.3502692 mm 20 KN 1° 5/3 KN 2° C 2° D A B CROSS SECTION Dimensions are in mm LOADING DIAGRAM ? 120 40 40 A B C D 1000mm 2000mm 1000mm -55/3 KN MB' C D BENDING DIAGRAM MB A B Σ Mc

Find the maximum bending stress in ksi for this beam if it is made from a W16x50 steel shape. If the steel yields at 50 ksi, will the beam support the loads shown without permanently deforming? Confirm the max moment in the beam by drawing the shear and moment diagram. 18 kip-ft 2 kip/ft 9 ft
