Adolphin propels itself through the water by moving its body and tail. to study the fluid motion a one tenth-scale model is made and used in a water channel. list any assumptions. c) if the maximum speed achievable in the water channel is 100 m/s, what actual dolphin speed does this correlate to? d) to travel at the speed you determined in a) the actual dolphin completes one swimming motion per second. how many swimming motions per second will the model dolphin complete?

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

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
