1)
In the condenser of the power plant, Ammonia is isobarically condensed to saturated liquid state with 615.2??? and ? = 0.9, the mass flow rate is 4 ?/h. The heat rejected from the condensing ammonia is added to heat water, which is heated from 277K to 281K. Whar is the mass flow rate of water in ?/h
2)
A flow of compressed liquid water at 15??? (In an advanced steam power plant), 308K is mixed adiabatically with a liquid-vapor mixture flow at the same pressure with quality of x=0.88 .The resulting mixture is in the saturated liquid state and the total mass flow is 5 ?/???. What is the mass flows of the incoming flows, and the entropy generation rate, and the work loss for the process (with respect to standard environment, ? = 298?)

- I have been working on this problem for a while but I need to figure out how to get the specific enthalpy when the refridgerant exits the system to find the mass flow rate of when the refridgerant exits the system but I don't know how to do thisarrow_forward1. Heat Transfer Problem: We want to generate steam at 300 C 20 bar at 1000 kg/min from water at 60 C, 20 bar. To do this we will use oil at 500 C which will leave the steam generator at 350 C. (Cp = 0.9 cal/g-C) What is the rate of oil required?arrow_forward3. We have steam at 10 bar flowing in a line. We open a valve attached to the line and the steam comes out to 1 bar at 100 C. a) is this possible? b) What is the state of the steam in the line ...compressed liquid, saturated mix, superheated vapor?arrow_forward
- A steady stream of steam passes through an adiabatic turbine. It enters at 10 MPa, 450 °C and 80 m/s and at the exit it is 500 KPa, 40% quality and 30 m/s. The mass flow of the steam is 12 kg/s. a) With the power that comes out of the system, 252 100 W bulbs can be lit. Calculate the efficiency of the system. b) What is the area of the duct at the entrance? c) What is the volumetric flow at the outlet? d) What is the temperature of the steam at the outlet?arrow_forwardi need the method of finding the answer and the full solution.
