A Small-sized Wind Turbine is schematically shown in Fig (a), and is delivering a maximum rated power of ( 50 KW ). This Wind Turbine is using " A Single-Stage- Spur- gearbox " to speed up the main Drive shaft speed from 20 rpm to 1400 rpm ( see Fig (b) ). In order to absorb shock loads , such gear box is suspended in space by two torque arms -as shown in Fig ( c ); which is attached to the turbine housing by a Bolted Joint, of 6 equally spaced Hexagonal bolts. requirements:

1- The Standard Design Procedure

2-Design of Torque arm,

3-Design of the Bolted Joint

4-Design of the used Spur gear Pair

5-Design of main Input Shaft together with its KEY

6-Select the Right Deep Groove Ball bearings; which are supporting the main input Shaft, and Finally

7-The Configuration of the Main Input Shaft (Product Concept, DFM, DFA, Dimensions, Fits, and Tolerances for mating parts)

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
