How to solve this question?

  1. Write down the steady flow energy equation for an open system control volume. Stating any assumptions you have made, apply this equation to

  1. A steam boiler
  2. A nozzle

                                                                                 

  1. Carbon dioxide enters a compressor with a mass flow rate of 0.5 kg/s. The compressor inlet pressure is 1 bar (absolute) and the inlet temperature is 300K. The outlet pressure is 6 bar (absolute) and the outlet temperature is 450K.
  1. Calculate the density of the carbon dioxide at the compressor inlet.

  1. Calculate the volume flow rate through the compressor.

  1. If a heat loss of 25 kJ/kg occurs during the compression process, and the specific internal energy of the carbon dioxide increases by 110 kJ/kg, calculate the input power to the compressor. [You may assume that all kinetic and potential energy effects are negligible]

Take specific gas constant for carbon dioxide R = 0.189 kJ/kg K

Draw a Flow chart and write a C++ program to solve the quadratic equation ax^2 + bx + c = 0 where coefficient a is not equal to 0. The equation has two real roots if its discriminator d = b2 – 4ac is greater or equal to zero. The program gets the three coefficients a, b, and c, computes and displays the two real roots (if any). It first gets and tests a value for the coefficient a. if...
