Problem 1: Steam at 200 °C and 10 bar is cooled under constant pressure until it becomes saturated liquid. a) What is the final temperature? b) How much heat is removed from the steam? c) Calculate the work involved in this process, if any. Problem 2: a) Water at 1 bar, 20 °C is heated at const P to produce steam with quality 95%. What is the amount of heat? b) What is the final state if the amount of heat is 2100 kJ/kg?
Calculate the percentage of solvent in the dried fabric by weight. What is the concentration of solvent in the dryer exhaust (in g/m3) if the exhaust is at 80 degrees C and 1 atm? The solvent has a molecular weight of 86.
The diagrams above show four Bode plots of uncompensated and compensated performance for a particular control system. Which diagram shows the effects of adding phase-lag compensation?
2. Alcohol is a diuretic agent, which increases urine production by reducing water reabsorption. Normal rate of water reabsorption is about 124 ml/min. Assume that the effect of alcohol on water reabsorption (in ml/min) is given by the following equa..
