At flow nozzle is to be installedin a 5-in type k copper tube carrying linseed oil at 77 f. a mercury manometer is to be used to measure the pressure difference across the nozzle when the expected range of the flow rate is from 700 galmin to 1000 gal/min. the manometer scale ranges from 0 to 8.0 in of mercury determine an appropriate diameter of the nozzle.

Apipe with an outside diameter of 15 cm is exposed to an ambient air and surrounding temperature of -20°c. the pipe has an outer surface temperature of 65°c and an emissivity of 0.85. if the rate of heat loss from the pipe surface is 0.95 kw per meter of length, the external convective heat transfer coefficient (h) is: (a) 12.5 w/m"k (b) 18.6 w/mk (c) 23.7 w/mk (d) 27.9 w/mk (e) 33.5 w/mk

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?

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