A condenser is to be designed to condense 225.0 kg of steam per hour at a pressure of 0.15 bar. A square array of 400 tubes, each of 6 mm in diameter, is available for the task. If the tube surface temperature is to be maintained at 26 degree Celsius, make calculations for the length of the tube
The outer surface of a vertical tube is 1.25 m long and outer diameter is 50 mm is exposed to saturated steam at atmospheric pressure. If the tube surface is maintained at 80 degree Celsius by the flow of cooling water through it, determine the rate of heat transfer to the coolant
Consider the above problem, find the rate at which steam is condensed at the tube surface
What is the value of characteristics length in turbulent film condensation?
Where, δ is length of the plate
What is the value of Reynolds number in terms of mass flow rate?
Where, δ is length of the plate and b id width of the plate
The relation between relative effectiveness of horizontal and vertical tubes as condensing surfaces is given by
For n-tubes in a vertical column of the tube bank pattern, identify the correct statement
Where, D is the diameter of a single tube in the bank
