Two oil tanks are connected by two 9-m-long pipes, as in fig. p6.26. pipe 1 is 5 cm in diameter and is 6 m higher than pipe 2. it is found that the flow rate in pipe 2 is twice as large as the flow in pipe 1. (a) what is the diameter of pipe 2? (b) are both pipe flows laminar? (c) what is the flow rate in pipe 2 (m3/s)? neglect minor losses.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false
