Approximate the skin friction drag on on a 1 m long by 60 cm diameter cylinder. it is located axially in a wind tunnel, when the air speed is 4.5 m/s. the pressure is atmospheric and the temperature is 50°c with (ρ =1.095 kg/m^3 and v =1900 x 10^-5 m^2/s).

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

Find the minimum film thickness for a journal bearing with the data below. shaft diameter, d-50 mm, clearance ratio, cdratio? 0.001, shaft speed, n 2000 rpm; bearing length. i 200 mm; eccentricity ration, ? -0.55. ( note, cdratio-ca/d) the minimum film thickness is um

Apiping systems consists of 6 m of 6-std type k and 12 m of 4-std type k, both drawn copper tubing. the system conveys ethylene glycol at a rate of 0.013 m3/s. the pressure drop across the system is to be calculated. there are two 90° elbows in the 6-in pipe, a reduction from the 6-in pipe to the 4-in pipe and four 90° elbows in the 4-in pipe. all fittings are soldered (same as flanged) and regular. the inlet and outlet of the system are at the same height.
