Underground water is being pumped into a pool whose cross section is 3 m x 4 m, while water is discharged through a 5-cm-diameter orifice at a constant average velocity of 5 m/s. If the water level in the pool rises at a rate of 1.3 cm/min, determine the rate at which water is supplied to the pool, in L/s.

If a particle moves along a path such that r : (3 sin t) m and ? : 2t rad, where t is in seconds. what is the particle's acceleration in m/s in 4 seconds? a)- 16.43 b)- 16.29 c)- 15.21 d)- 13.79

Describe briefly, the concept of mass production in modern industrial system.

Adrawing operation is to be performed on a perfectly plastic material with strength coefficient- 100 mpa and strain hardening exponent-0. neglect redundant strain. die/work material friction coefficient=0 a)-what is the drawing stress? if this stress is a function of the area reduction, state so. b)-what is the strength of the material after drawing? if this strength is a function of the area 4. reduction, state so. c)-what is the maximum area reduction possible?
