Chapter 16.6, Problem 77P

An ammonia–water absorption refrigeration unit operates its absorber at 0°C and its generator at 46°C. The vapor mixture in the generator and absorber is to have an ammonia mole fraction of 96 percent. Assuming ideal behavior, determine the operating pressure in the (a) generator and (b) absorber. Also determine the mole fraction of the ammonia in the (c) strong liquid mixture being pumped from the absorber and the (d) weak liquid solution being drained from the generator. The saturation pressure of ammonia at 0°C is 430.6 kPa, and at 46°C it is 1830.2 kPa.

An aqua ammonia absorption plant operates between pressures at 206.8 and 1378 kPaa. The strongsolution enters the generator saturated at 82.2°C and the weak solution leaves the generator saturated at93.3°C. Saturated vapor leaves the generator with a concentration of 0.993 kg NH3 /kg mixture. Assuming thatthe strong solution leaving the absorber is saturated, neglecting pump work and heat losses, calculate perkg/min flow of refrigerant through the evaporator:a. the mass flow of strong solution entering the generator in kg/minb. the mass flow of weak solution leaving the generator in kg/minc. the enthalpy of the weak solution entering the absorber in kJ/kg weak solution and the heat rejected in the absorber in kW Saturated liquid at 1378 kPaa and 82.2°C has a concentration of 0.46 kg NH3 /kg mixture and an enthalpy of209.2 kJ/kg of mixture, saturated liquid at 1378 kPaa and 93.3°C has a concentration of 0.41 kg NH3 /kg mixtureand an enthalpy of 255.68 kJ/kg of mixture, saturated liquid…

Problem 13.053 Isobaric Heating A mixture of nitrogen and carbon dioxide has a carbon dioxide mass fraction of 50 percent. This mixture is heated at constant pressure in a closed system from 120 kPa and 30°C to 180°C. Calculate the work produced during this heating in kJ/kg. The universal gas constant is Ru= 8.314 kJ/kmol-K. Use the table containing the molar mass, gas constant, and critical-point properties. The work produced during this heating is kJ/kg.
