The change of the motor moment (Mm) and the resistance moment (Md) in a 2? period machine with a conservative force field are as follows.
?? = 100? / ?, 0 ≤ ? <? (Nm)
?? = 200 - 100? / ?, ? ≤ ? <2?
?? = 50, 0 ≤ ? <2?
The average speed of the machine is 100 rad / s and the variable part of the moment of inertia is ?? = (0.003) sin (2?). If the speed unevenness is 1% and the current flywheel value is 0.4 kgm ^ 2, find the flywheel amount that should be added to the machine.

develop an efficient approach for heat recovery and cogeneration the system should be unique and the idea is not being used by anybody else it should be free from copyright you are supposed to discuss commercially available waste heat recovery devices and how your system is different than the existing the proposed system should be unique and should not be used earlier draw the schematic explain the features and the proposal of 8 pages

carry out steady state and dynamic simulation of plate heat exchanger for to Facebook share using 41077 your study should deal with the steady state and dynamic simulation of the plate fin heat exchanger its in like it should in light and some aspect of the modelling of such a complex system in a transient and especially the impact of the numerical treatment illustrate application and sketch the importance of dynamic studies in complement with steady state

1. a What are the most important aspects to be considered in preparing reliability specifications?

b Write an outline reliability specification for (i) a domestic TV set, (ii) a fighter aircraft, and (iii) a gearbox bearing.

Mark the following statements as True or False.

1) Substitutional vacancy atoms are present in the region of the dislocation where compressive stresses are present.

2) If the Burgers vector of a screw dislocation is along the y - direction, then displacements surrounding the stationary screw dislocation are also in the same direction.

3) External tensile stresses generates vacancies in the material when edge dislocations are present.

The research is to be carried out to analyse the performance of evaporative cooler model with simple surfaces and honeycomb structured using R 290/R410 c with blend mixture. it is to be tested over the 25% load, 50% load, 75% load and 100% load conditions....
First propose a unique arrangement for the testing rig. and then formulate a mathematical model using fortran 77 performe simulation of the system and validate the results using available standard results......

coding is to be done in the Fortran 77 only. no other software will be entertained...

Air undergoes a polytropic process in a piston–cylinder assembly from p₁ = 1 bar, T₁ = 295 K to p₂ = 9 bar. The air is modeled as an ideal gas and kinetic and potential energy effects are negligible.

For a polytropic exponent of 1.2, determine the work and heat transfer, each in kJ per kg of air,
(1) assuming constant c_v evaluated at 300 K.
(2) assuming variable specific heats.

W/m = -187.211 kJ/kg

Q/m= -93.563 kJ/kG

Determine the heat transfer, in kJ per kg of air, assuming variable specific heats.

Apply systems thinking as a methodology to how you intend investigating and assessing your Power Generator Speed Breaker product, following, and documenting all the 7 steps to Systems Engineering (SE). By taking your product through the stages of systems engineering, Conceptual Design, Preliminary Design, and Detail Design and Development.

0.75 kg of refrigerant-134a at 120 kPa and 20°C initially fills a piston-cylinder device. Heat is now transferred to the refrigerant from a source at 150°C, and the piston which is resting on a set of stops, starts moving when the pressure inside reaches 140 kPa. Heat transfer continues until the temperature reaches 90°C. Assuming the surrounding to be at 25°C and 100 kPa, determine (a) the work done, (b) the heat transfer, (c) the exergy destroyed, and (d) the second law efficiency of this process.
