The lifetime of a driver circuit at the front end of device is modeled as Y and the lifetime of the device is modeled as X. It is obvious that the device will cease to operate when the driver circuit fails while the converse is not true. The device may fail even when the driver circuit is working. The joint density of these two life times is ( , exp ,0 ) 10 y f xy K x y   = − < < <[infinity]     Obtain the value of K so that f(x, y) is a valid density. Obtain the mean life times of the driver circuit, device. If the device fails, what is the expected lifetime of the driver circuit?

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
