Air undergoes a constant pressure process from 300K to 500K in a piston cylinder. Determine the heat transfer for this process in [kJ/kg). You may assume that air behaves as an ideal gas with constant specific heats.

At 500oC, the diffusion coefficient of Cu in Ni is 1.3 x 10-22 m2/s, and the activation energy for diffusion is 256,000 J/mol. From this information, determine the diffusion coefficient of Cu in Ni at 900 oC. (R = 8.314 J / (mol K)) 0oC = 273 K

Explain how load cell can be used for force measurement.

A solar radiation flux of 700 W/m2 is absorbed in a metal plate that is perfectly insulated on the back surface.

An optical mouse originally cost $31.85. Before it was removed from the store, it underwent the following changes in price.

The controller can be considered the brain of closed loop system

What is the main role of matrix in composites! a) - to transfer stress to the other phases b) - to protect phases from environment c) - to reduce the hardness d) - to enhance ductility

Our goal is to design a traffic-light controller with the following properties; it lights up the green light (output G) for 15 seconds, followed by the yellow light (output Y) for 9 seconds, then the red light (output R) for 12 seconds.

A 25-kg cast-iron wood-burning stove contains 5kg of soft pine wood and 1 kg of air. All the masses are at room temperature, 20 degree C, and pressure, 101 kPa. The wood now burns and heats all the mass uniformly, releasing 1500W.

The power supply converts the wall outlet AC power into DC power. T or F
