Concept explainers

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.

7.43 Liquid sodium is to be heated from 500 K to 600 K by passing it at a flow rate of 5.0 kg/s through a 5-cmID tube whose surface is maintained at 620 K. What length of tube is required?
A 2.5-cm-OD, 2-cm-ID copper pipe carries liquid oxygen to the storage site of a space shuttle at -183Cand0.04m3/min. The ambient air is at 21C and has a dew point of 10C. How much insulation with a thermal conductivity of 0.02 W/m K is needed to prevent condensation on the exterior of the insulation if hc+h=17W/m2 K on the outside?
A 0.013 m- o.d., 1.5-m-long tube is to be used to be condense steam at 40,000 N/m^2, Tsat=349K. Assume that the average tube-wall temperature is 325 K.The average convection coefficient for this tube in the horizontal position. is?
Heating Air by Condensing Steam. Air at a pressure of 101.3 kPa and 288.8 K enters inside a tube having an inside diameter of 12.7 mm and a length of 1.52 m with a velocity of 24.4 m/s. Condensing steam on the outside of the tube maintains the inside wall temperature at 372.1 K. Calculate the convection coefficient of the air. (Note : This solution is trial and error. First assume an outlet temperature of the air.)
Saturated, pure steam at a temperature of 170 oC condenses on the outer surface of avertical tube of outer diameter 2 cm and length 1.5 m. The tube surface is maintained at auniform temperature of 150 oC.Calculate:a) the local film condensation heat-transfer coefficient at the bottom of the tube. b) the average condensation heat-transfer coefficient over the entire length of the tube. c) the total condensation rate at the tube surface.
a film-type condenser consists of a packed bed of 3-cm diameter spheres with a voidage of 35%. water sprayed onto the bed at 60oC is used to condense steam entering at the base at a saturation temperature of 100oC. How deep must the bed be to ensure complete condensation of the steam, and what is the outlet temperature of the water? (Use water properties based on the mean of the inlet and outlet water temperatures, and iterate if necessary)
I need help on this question: (This question requires the use of Roger & Mayhew Steam Property Tables) Saturated steam at 1 atm is condensed on the external surface of a copper tube withan outside diameter 16 mm and tube wall of thickness 0.5 mm. The tube is cooledinternally by water with a mass flow rate of 0.06 kg/s, which in turn is raised intemperature from 15 oC to 60 oC as it flows through the tube. (Take the heat-transfer coefficient at the condensing side as 10.0 kW/m2K and the isobaric specific heat-capacity of water as 4180 J/kg K.) a) To calculate the heat transfer rate to the cooling water b) To calculate the length of the tube c) Comment on how to enhance heat transfer in this case.
