Liquid water flows through a steady state nozzle and the vel

Liquid water flows through a steady state nozzle, and the velocity at the exit is 9 times the inlet velocity. The ratio of the inlet-to-outlet DIAMETER is: 0.111 9 rho_2/rho_1 3 0.333 For the scenario described in Question 2, above, an equation representing this relationship could be: rhoA_EV_E=rhoA_eVe m_i=m_e A_iV_i/vi=A_eV_e/v_e A_i/V_e=A_e/V_i None of these All of the these (a-d) Fill In The Blank. Fill in each portion for the following questions. Steam is expanded in a reversible turbine, which loses heat to the surroundings. The entropy of the steam will always____in proportion to the heat transferred._____is the equation for the \"Irreversibility\" of a process, which describes____. The constant-volume specific heat relates a temperature change in a process to the change in______In a Rankine steam power plant, water goes through these general thermodynamic processes to complete this ideal cycle: A_____process using a work input to increase the water____. A____process generates____from liquid water. An_____process in a piston or turbine receives_____out of the engine. A____rejects heat out of the system and turns the steam back into______.

Solution

A₁ V₁=A2V2   A₁ /A₂ =(D₁ /D₂)^2 =V2 / V₁ =9; (D₁ /D₂)=3

answer for 5 is option d

answer for 6 is option f

since fluid is incompressible. density remains constant. law of mass conservation can be applied at both exit and inlet . mentioned in a,b, c options. V is the velocity and v is the specific volume which is reciprocal of density
