The rigid tank has a volume of 0.06 m3 and initially contains a two-phase liquid-vapor mixture of H2O at a pressure of 15 bar and a quality of 20%. As the tank contents are heated, a pressure-regulating valve keeps the pressure constant in the tank by allowing saturated vapor to escape. Neglecting kinetic and potential energy effects.
Determine the total mass in the tank, in kg, and the amount of heat transfer, in kJ, if heating continues until the final quality is x = 0.5
Plot the total mass in the tank, in kg, and the amount of heat transfer, in kJ, versus the final quality x ranging from 0.2 to 1.0
Calculate the net cycle work in kJ assuming air is an ideal gas with constant specific heats.
All calculations and assumptions must be provided together with a full explanation of all the terms
Important information about Compressive Stress, A circular cross sectional bar with a diameter of 3.25 inches is loaded with a uniform axial compressive load of 22,750 pounds. What is the compressive stress along a cross section of the bar?
Wheel of radius r is driven by an arm OA. It is driving (without slip) wheel of a radius r2 which is fixed to a drum of radius r1. Load G is attached to the rope which winds on the drum. Calculate the speed of load G if the arm OA moves at n rev/m..

8 x product engineering and design review (week 2 – 12), ~3 pages per item which must contain a brief description of the product then delve into concepts such as materials selection, manufacturing methods, life cycle analysis, recyclability and overa..
Two infinite parallel plates are separated by a distance h. The space between them is filled with a Newtonian fluid: density (rho), viscosity (mu). The lower plate is fixed
An air heater may be fabricated by coiling Nichrome wire and passing air in cross flow over the wire. Consider a heater fabricated from wire of diameter D=1 mm, L= 2m, electrical resistivity rho=10^-6 ohms, thermal conductivity k=25W/mK, and emiss..
Calculate the change in internal energy of the gas. Remember it is an ideal gas in a constant temperature bath.
Working with processes of an application to ideal gases., While its temperature remains constant at 80 degrees F, 2.5lb of a certain gas, whose cp=0.28 and cv=0.2Btu/lb-degreeR
