The data listed below are claimed for power cycles operating between hot and cold reservoirs at 1000 k and 400 k, respectively. for each case determine whether such a cycle is in keeping with the first and second laws of thermodynamics. (a) qh 5 300 kj, wcycle 5 160 kj, qc 5 140 kj. (b) qh 5 300 kj, wcycle 5 180 kj, qc 5 120 kj. (c) qh 5 300 kj, wcycle 5 170 kj, qc 5 140 kj. (d) qh 5 300 kj, wcycle 5 200 kj, qc 5 100 kj.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges
