A mass of 5 kg of saturated liquid vapor mixture of water is contained in a piston cylinder device at 100 kPa, initially 2 kg of water is in the liquid phase and the rest is in the vapor phase.Heat is now transferred to the water and the piston which is resting on a set of stops, starts moving when the pressure in side reaches 200 kPa, heat transfer continues until the total volume increases by 20%, determine a. the initial and final temperature b. the mass of liquid water when the piston first starts moving c. the work done during the process d. show the process in P-V diagram

Write a user-defined MATLAB function that uses classical fourth order Runge-Kutta method to solve a first order ODE problem dydx = f(x, y) in a given interval a ? x ? b with initial condition y(a) = y0 and step size of h. For function name and arguments, use [x,y] = myrk4(f, a, b, h, y0)
Check your function to find the numerical solution for dydx=?1.2y+7e^(?0.3x) in the interval 0 ? x ? 4 with initial condition y(0)=3. Run your program three times for h=1.0, 0.1, 0.01 and plot all results along with analytical solution y=(70/9)*e^(?0.3x)?(43/9)*e^(?1.2x) on the same figure.

The pressure p and volume v of a given mass of gas are connected by the relation
k=(p+a\v^2)(v-b)
where a, b, and k are constants.
Using the composite trapezoidal method, write a MatLab script to approximate the work done by the gas in expanding from an initial volume to a final volume. Express p in terms of v.
Where W = Integral (Pdv)

Regarding the fracture mechanism of metals, polymers and ceramics
(a) Explain why FCC metals show a ductile fracture even at low temperatures while BCC metals do not.
(b) What is crazing? What can you say about the Poisson’s ratio of the crazed material?
(c) Generally, in ceramics, intergranular fracture is preferred to cleavage fracture; however, in metals, transgranular fracture is the preferred mechanism for brittle failure. Why? Use a physical reason supported with an equation in your answer.

13.75 Air enters the compressor of a simple gas turbine power plant at 70F, 1 atm, is compressed adiabatically to 40 lbf/in.2, and then enters the combustion chamber where it burns completely with propane gas (C3H8) entering at 77F, 40 lbf/in.2and a molar flow rate of 1.7 lbmol/h. The combustion products at 1340F, 40 lbf/in.2 enter the turbine and expand adiabatically to a pressure of 1 atm.The isentropic compressor efficiency is 83.3% and the isentropic turbine efficiency is 90%. Determine at steady state
(a) the percent of theoretical air required.
(b) the net power developed, in horsepower.

Provide a summary of the ASTM E112–12 standard’s definition of the grain size number G. Your summary should give the precise mathematical definition for G. Your summary should also supply a conceptual description of G; this description should not require significant technical background to understand. • Provide a summary of the Lineal Intercept Procedure described in the ASTM E112–12 standard. Your summary should give sufficient detail that someone could use it to compute the grain size number G without any other information.
Overall what exactly is G? What is ASTM E112-12? What is the lineal intercept procedure?
