Properties of Pure Substances

A substance with fixed chemical composition throughout is called a pure substance like water, air, and nitrogen. A pure substance does not have to be a single element or compound. A mixture of two or more phases of a pure substance is also a pure substance as long as the chemical composition is the same for all phases. These substances mainly have a constant/ uniform composition. The substances also have fixed boiling and melting points. A pure substance takes part in a chemical reaction to form predictable products.

Question

b) The high pressure units on a steam plant operate at 10bar (gauge), and the condensate is sub-cooled by 9.5K. If the mass flow rate of condensate is 10 kg/s, use the provided steam tables to determine how much saturated steam at 1.5 bar this condensate could produce. Note it is sufficiently accurate for high pressure condensate, as in this question, to assume that the specific enthalpy is the same as for the saturated liquid at the same temperature.

An unknown ideal gas at 53 deg F and 3.3 in Hg (gauge) is flowing through an irregular duct. To determine the flow rate of the gas, carbon dioxide, from a modular carbon dioxide tank, is passed into the gas stream. The gas analyzes 1.2% CO2 before and 3.4% after addition. The tank is on a scale and found to lose 12 lb in 10 minutes; What is the flow rate of the ideal gas in ft^3/minute?

Apply the ideal gas equation and calculate the volume (units: m3) for a single tank in at its fully pressurised state inside the plant room.
PLEASE DO NOT USE PSYCHROMETRIC CHART. THANK YOU In the diagram below inlet air is drawn over a pool of liquid water in a steady-state, steady-flow isobaric process. Evaporation on the pool resultsin saturated air at the exit. The pool of liquid water is assumed to be at the same temperature as the exitair. Discharge fans at the exit provide a volumetric flow rate of 800,000 ft3/min. Problem #2: Assume that the R134a chiller is turned off such that Qout = 0, but the evaporative coolersystem continues to operate. Determine:a) The exit temperature, T2 (°F)b) The mass flow rate dry air through the system (lbm/sec).c) The rate of liquid water resupply required for continuous operation (lbm/hour).
Completely solve and provide the diagram. Box the final answer. Write legibly 4. A single effect water evaporator operating at 125 kPa abs vapor pressure. Motive steam is available for evaporation at 1.0 MPa with 90% vapor content, what is the mean temperature difference?
