Trb Mechanical Solved Enquiry On Laminar Catamenia Maximum Velocity

Going to write the TRB Polytechnic Lecturer Exam 2017 ? Want unopen to solved questions for Mechanical Engineering? Here is a enquiry which was asked inwards the previous yr examination (Engineering College Exam) held inwards 2016. This enquiry comes nether the Syllabus of Fluid Mechanics in addition to Machinery (Laminar Flow). The enquiry is non widely available inwards the internet. No answer tin survive establish inwards the network for the next enquiry in addition to therefore nosotros convey come upwards hither amongst a solution which volition plough over an sentiment for those who are preparing the TRB examination really seriously. Here is the enquiry in addition to its solution.

Question: Laminar Developed menstruum at an average velocity of v m/sec occurs inwards a pipage of ten cm radius. The velocity at v cm radius is, 
A) 7.5 m/sec B) v m/sec C) 2.5 m/sec  D) ten m/sec

The Solution inwards detail:
You volition uncovering the explanation for the answer below. As the maximum velocity occurs at the centre for laminar flow, the calculation is made accordingly. See the attachment for solution.
