Question

i need the answer quickly

In a closed cycle gas turbine, there is two stage compressor and two-stage
turbine. All the components are mounted on the same shaft. The pressure
and temperature of air at inlet to the first stage compressor are 1.5 bar
and 20°C respectively. The maximum cycle pressure and temperature are
limited to 750°C and 6 bar. A perfect intercooling and reheating are used
between the compressors and the turbines. A regenerator whose
effectiveness is 0.7 was employed. Assuming the compressors and
turbines efficiencies as 0.82, calculate:
a. Thermal efficiency of the cycle.
b. Mass of working fluid for a power output of 350 kw.
Assume the working fluid is air has C, = 1.005 kJ/kg K, y = 1.4.

Problem 3: A small gearing system in your brand-new 3D printer fails as you were printing, leading to an overload in the motor and a fire in your home. The fire spreads, burning half of Everglades National Park in the worst environmental disaster in US history. The printer company blames you! Stating that you must have been misusing the printer some- how. Use your engineering knowledge to "show those jerks you mean business!" You investigate and find a serial number on the gears and type it into Google, finding the company that manufactures the gears. Their website provides some info that this series of gear is made from AISI 4340 steel and the yield strength is 125 kpsi. Assuming each gear tooth acts as a small cantilever, prove to the 3D printer company that they are liable for the fire. oct # Gear Information Gear radius (r): 1.00 in Tooth length (1): 0.15 in Tooth height (h): 0.15 in Tooth thickness (b): 0.1 in Angular velocity (w): 0.1 rad/s Motor Information Power (H): 0.009 hp 1…

A machine makes two components; call them types A and B. It takes 250 seconds to switch production between the component types. During that time, no production occurs. When in production, each unit of A or B requires 0.5 second to be completed. The two components, A and B, are combined in an assembly process to make a final product; call it C. The assembly step can combine the two components into 1 unit every 2 seconds, or 30 units per minute. Assume there is ample demand. Suppose the machine rotates between one batch of 1,000 units of A and 1,000 units of B. What is the average inventory of B components? answer:______units
