ASEM 12/6/2015 Q1/ A stream of warm water is produced in a steady flow mixing process by combining 1.0 kg/s of cool water at 25 °C with 0.8 kg/s of hot water at 75 °C. During mixing, heat is lost to the surroundings at the rate of 30 kJ/s. What is the temperature of the warm water stream? Assume the specific heat of water constant at 4.18 kJ/kg.K.
200 m3/min is passed through the adiabatic humidifier. The condition of the air at inlet is 40C db and 15% RH and the outlet condition is 25C db and 20C wb. Find the amount of the water vapor added to the air per minute.
2) In a well-insulated fixed-volume closed vessel, there is initially 5 kg of saturated liquid-vapour mixture water at 100 kPa pressure. In this state, one quarter of the total mass is in the vapor phase. Then, the electric heater in the container operates and a current of 8 A flows through the heater plugged into a 110 V outlet. How long will it take to evaporate all the liquid in the container? Plot the phase change in the T-v diagram showing the saturation curves.
Saturated steam at 10 bar pressure is supplied to increase the temperature of the feed natural gas from its inlet temperature of 30°C to within 15°C of the steam outlet temperature. All steam properties can be verified in the steam table, attached. Evaluate the mass flow rate of the steam supplied, if about 20% of the steam is still uncondensed at the exit. The relevant properties of Natural gas (NG) are as follows: NG Flow Rate = 1500 kMol/hour Average specific heat Capacity of NG = 40 kl/kMol.°C.
Steam (H2O) enters a turbine at 35 m/s and specific enthalpy of 3500 kJ/kg. Thesteam leaves the turbine as a mixture of vapor and liquid having a velocity of 60m/s and a specific enthalpy of 2400 kJ/kg. If the flow through the turbine is steady,adiabatic, and changes in elevation are negligible, calculate the work output per unitmass (kJ/kg) for the turbine.
