i need the The shaft is supported by a smooth thrust bearing at AA and a smooth journal bearing at BB. Draw the shear diagram for the shaft. Follow the sign convention.

4- In the system shown in the figure, the water velocity in the 12 in. diameter pipe is 8 ft/s. Determine the gage reading at position 1. Elevation 170 ft 1 Elevation 200 ft | 8 ft, 6-in.-diameter, 150 ft, 12-in.-diameter, f = 0.020 f = 0.020 A B Hints: the minor losses should consider the contraction loss at A and the expansion loss at B.

Consider a glass window (Hight = 1.2 m, Width = 2 m). The room thatfaces the window are maintained at 25 o C. The average temperature ofthe inner surface of the window is 5 o C. Calculate the total heat transferrate from through the window a) IdenCfy what type(s) of convecCon is important (circle one). • external forced (Chapter 7)• internal forced (Chapter 8)• natural convecCon (Chapter 9)• boiling and condensaCon (Chapter 10)b) IdenCfy the necessary equaCon(s) needed to solve the problem. c) IdenCfy important fluid properCes you need to solve the problem. d) Calculate the total heat transferred.

Water is condensing on a square plate (0.5 m x 0.5 m) placed verCcally. If the desired rate ofcondensaCon is 0.016 kJ/s, determine the necessary surface temperature of the plate at atmosphericpressure. Assume the film temperature of 90 o C for evaluaCon of fluid properCes of water and thesurface temperature of 80 o C for the evaluaCon of modified latent heat of vaporizaCon

Water at 20 o C enters the 4 cm-diameter, 14 m-long tube at a rate of 0.8 kg/s. The surfacetemperature of the pipe is maintained at 165 o Cby condensing geothermal stream at the shellside of the heat exchanger. Use water properCesat 85 o C for all calculaCons.(a) Show that the water flow is turbulent and thermally fully developed. (b) EsCmate the heat transfer coefficient for convecCve heat transfer from the pipe to the water. For a fully developed turbulent flow within the smooth pipe, the Nu number can becalculated from the following equaCon:(c) Calculate the exit temperature of the water. (d) Share your opinion on whether the use of water properties at 85°C is appropriate. Yes or No because:
