Saturated liquid steam at 2 MPa steadily enters a valve where it is throttled to 0.3 MPa. The inlet and outlet diameter is 1 cm. The flow rate is 0.012 kg/s. Determine the outlet density [kg/m3] of the steam. Also show that it is reasonable to neglect the kinetic energy effects. Show the process on a T-v state diagram.
The cold cranking amperes (CCA) of a conventional lead-acid automobile battery is the amount of current the battery can provide at 0°F for 30 seconds and minute in at least 1.2 volts per cell (or 7.2 volts for a standard 12-volt battery). If a batter..

An oil engine operating on the ideal diesel cycle has the overall compression ratio of 16:1, and the adiabatic expansion ratio or 8.75. The pressure and temperature at the beginning of adiabatic compression are 102.5 Kpa and 297K, respectively and th..
An advanced type supercritical power plant has turbine inlet steam at 7000 psia and 1400F, double reheat at 1600 psia and 400 psia, both to 1200F, and condenser at 1psia. The three turbine sections have polytropic efficiencies of 0.93, 0.91 and 0.89 ..
A steel rod of radius 0.01m and length 2m is pulled on with a tensile force of 200,000 N, the bar stretches to a length of 2.08 m. The radius of the bar is reduced to 0.0099 m. Determine the stress, strain, Young’ modulus (E), and Poisson’s ratio (n)..
