Arigid tank whose volume is 0.5 m3, initially containing ammonia at 20°c, 1.5 bar, is connected by a valve to a large supply line carrying ammonia at 12 bar, 200°c. the valve is opened only as long as required to fill the tank with additional ammonia, bringing the total mass of ammonia in the tank to 143.4 kg. finally, the tank holds a two-phase liquid–vapor mixture at 20°c.

determine the heat transfer to the ammonia in the tank from the surroundings, in kj, ignoring kinetic and potential energy effects.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
