What do you mean by condensation? Explain in details.

Saturated, pure steam at a temperature of 170 oC condenses on the outer surface of a vertical tube of outer diameter 2 cm and length 1.5 m. The tube surface is maintained at a uniform temperature of 150 oC. Calculate: the local film condensation heat-transfer coefficient at the bottom of the tube.   the average condensation heat-transfer coefficient over the entire length of the tube. the total condensation rate at the tube surface.

How much much heat must be supplied to water at 180 degrees celcius to make 1 kg of wet steam at 9000 kpa , having a dryness fraction of 80% ? .

Pre-lab 8: Cold Engine The experimental setup for this week's lab consists of a syringe connected to a metal can (reservoir), a cold bath (water - ice mixture) and a "hot" bath (water at room temperature). A schematics of the syringe - reservoir system is shown below. Plunger of mass m Filled with gas (air) Syringe of volume Vcor VH - Volume Vo includes tube + Metal can -Metal can submerged in water of temperature Тс or TH. Tube Stopper Figure 1: Schematic of the syringe - reservoir system. The syringe is essentially a glass cylinder fitted with a movable piston (plunger). The markings on the syringe indicate the volume of gas in the syringe, but do not include the additional, unknown volume, Vo, in the gas can and tubing.
