A dual cycle operates with an air intake of 1 bar and 323K.
Thecompression ratio is 15:1 and the maximum pressures and temperaturesreached in the cycle are 75 bar and 2473K.
Calculate the pressure, specific volume and temperature at the end ofeach process in the cycle and the thermodynamic efficiency of the cycle.

A car accelerates from rest along a straight section of road. It starts at position s = 150 m and reaches a speed of 20 m/s at position s = 200 m. It is proposed that this acceleration, a, can be modelled as being a function of position, s, in the fo..
Outdoor air leaks into a building through cracks in the walls at the rate of 700 m3/h (this is infiltratation). The outside air is at a temperature of -16.1C and a humidity ratio of 0.001 kgv/kga. The density of the outside air is1.4 kg/m3. The indoo..

An air conditioning system is used to maintain a house at 70F when the temperature outside is 90F. If the air conditioning system draws 5 hp of power when operating, determine the maximum rate of heat removal from the house that it can provide.
a sample of tungsten w contains an edge dislocation. w can be treated as elastically isotro pi c and the dislocation is
A particle travels around a circular path having a radius of 66m. It is initially traveling with a speed of 10 m / s and its speed then increases at a rate of v = (0.05v) m /s2. Determine the magnitude of the particle's acceleration four seconds late..
