Acup of coffee of volume 0.3 l is heated from a temperature of 25 ? c to 65 ? c at a pressure of 100 kpa. determine the change in the internal energy (? u), enthalpy (? h), and entropy (? s). assume the density and specific heat of coffee to be 1100 kg/m3 and 4.1 kj/(kg? k) respectively. determine the change in the internal energy (? u), enthalpy (? h), and entropy (? s).

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Give heat transfer applications for the following, (i) gas turbines (propulsion) ) gas turbines (power generation). (iii) steam turbines. (iv) combined heat and power (chp). (v) automotive engines
