A fluid is held between a lower place of temperature T1 and an upper place of temperature T2; the distance between the two plates is L. The lower plate moves at a constant velocity V while the upper one is at rest. Find the steady-state temperature distribution in the fluid. Assume constant properties and neglect end effects.
a) What is the temperature and state of the steam in the pipe? b) What is the quality of the steam in the pipe?
the refrigerant is now heated at constant pressure until its temperature rises to 333k. calculate the work done during this process.
The wheel of a crane lift is rolling on a flat rail. The radius of the wheel is 4 in, the contact length and force are 2.5 in and 1 ton respectively, and E = 30 MPa and ν = 0.3 for both parts. Determine (a) the maximum contact pressure, (b) the wi..
Wheel of radius r is driven by an arm OA. It is driving (without slip) wheel of a radius r2 which is fixed to a drum of radius r1. Load G is attached to the rope which winds on the drum. Calculate the speed of load G if the arm OA moves at n rev/m..
