The truncated nozzle shown in the figure below is used to monitor the mass-flow rate of air in a pipe. The area of the nozzle is 3 cm². The total pressure and total temperature measured upstream of the nozzle in the pipe are 300kPa absolute and 20°C. The pressure downstream of the nozzle (back pressure) is 90 kPa. Absolute. Calculate the mass-flow rate.

Gravity is just the ratio of density of a material to water : A fan jumps into a swimming pool in an attempt to drown her sorrows. She is able to float on her back...in a position that is neutrally buoyant...so that she can continue to breathe through her mouth. Believing that 70% of her body is composed of wat..

Contained is a gas-tight frictionless piston-cylinder : A mass of 2.2 kg of helium at 381 kPa and -253oC is contained is a gas-tight frictionless piston-cylinder. The gas is expanded to a final pressure of 74 kPa in a poly tropic process where n = 1.667. Compute the work done (output positive) in the proc..

Condensed to a saturated liquid in a piston-cylinder device : Maturated water vapor at 800 kPa is isothermally condensed to a saturated liquid in a piston-cylinder device. Calculate the amount of heat transferred during this process.

Calculate the diffusion coefficient if the diffusion flux : A sheet of BCC iron 1.7-mm thick was exposed to a carburizing atmosphere on one side and a decarburizing atmosphere on the other side at 725°C. After having reached steady state, the iron was quickly cooled to room temperature. The carbon concentrati..
