Consider an ideal Brayton cycle executed between the pressure limits of 1,154 kPa and 100 kPa and temperature limits of 293 K and 1,047 K with air as the working fluid. Determine the turbine work output (kJ/kg) of the cycle (to the nearest unit value) using cold-air-standard assumptions.

What is the main objective of using reheat rankine cycle?

An engine, weighing 3000 n, is supported on a pedestal mount. it has been observed that the engine induces vibration into the surrounding area through its pedestal at the maximum operating speed. determine the stiffness of the dynamic vibration absorber spring in (n/m) that will reduce the vibration when mounted on the pedestal. the magnitude of the exciting force is 250 n, and the amplitude of motion of the auxiliary mass is to be limited to 2 mm note: in this question type-in right numbers, no decimals, no fractions, no unit. approximate to right number if needed

Consider airflow over a flat plate of length l = 1.5 m under conditions for which transition occurs at le = 0.9 m based on the critical reynolds number, re, e = 5 x 10. evaluating the thermophysical properties of air at 400 k, determine the air velocity. (hint: use the tables to find the properties of air)
