First you must solve this matrix manually and send the manual solution to me. (you must submit the manual matrix first) then you can start to develop your c++ program that can solve (any matrix) up to 15 equations with 15 unknowns. your program will be tested with a different matrix than the one given to you. your program should be able to read in the text file solve the the result on the screen as well as write the results to a text file. you dont have to do back substitution only solve for the value of one varible. there is information in teacher's hints on reading the two dimensional array into your program.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned
