An ideal air-standard Brayton cycle operates at steady state with compressor inlet conditions of 300 K and 100 kPa and a fixed turbine inlet temperature of 1700 K. For the cycle,
(a) determine the net power developed per unit mass flowing, in kJ/kg, and the thermal efficiency for a compressor pressure ratio of 8.
(b) plot the net power developed per unit mass flowing, in kJ/kg, and the thermal efficiency, each versus compressor pressure ratio ranging from 2 to 50.
how long will it take the puck to slow down to a speed of 1m/s and how long will it take for the puck to stop completely? How far will the puck travel before it slows to 1m/s? You can assume the table is very very long.
A square bar of side 20mm and length 2m is under a tensile load of 400N. Then the Normal stress is _____ MPa and the Maximum Shear stress is _____ Mpa. If the modulus of elasticity is 200GPa, then net deflection of the bar is ______m and the strain i..
An oil engine operating on the ideal diesel cycle has the overall compression ratio of 16:1, and the adiabatic expansion ratio or 8.75. The pressure and temperature at the beginning of adiabatic compression are 102.5 Kpa and 297K, respectively and th..
