Calculate heat transfer rate, Q. Q is measured in units of energy per unit time, such as BTU/hr or Watts. For a wall of uniform thickness d, with a thermal conductivity of k, an area of A, a hot temperature, Thot, and cold temperature, Tcold, solve Q with the following equation:...
How to calculate the heat transfer rate of the condenser and evaporator at different water mass flow rates? Show with examples.There are 2 steps to solve this one. Solution Share Answered by Mechanical engineering expert127 solutions Step 1 T...
Convective heat transfer resistance: The heat transfer coefficient can be improved by increasing the flow rate and disturbance to the fluid. IV. Design and Selection of Tube Heat Exchangers The core of the design and selection of tubular heat exchanger is to calculate the heat transfer area of t...
Where ṁ is the mass flow rate of the material (kg/sec). Knowing the heat transfer rate (q̇) it is possible to calculate the mass of steam needed by: Where ms is the required mass flow rate of steam (kg/sec) he is the steam evaporation energy or latent heat (kJ/kg), ...
sir i am working on cooling load calculation but I have one problem that how I calculate heat flow rate of heater of a machine? please suggest formula. Jim Miller 2019-10-10 at 3:50 pm We are looking at a ductless We are looking at a ductless system for our church sanctuary and meet...
How can I calculate entropy or entropy generation in CFD-Post for flow (incompressible) in pipe from fluid flow and heat transfer fields (i.e. solving momentum and energy equations)? I didn't find much in ANSYS documentation except a formula "s-s_ref=c_p*log*(T/T_ref)" for constant...
How do you calculate ventilation needed in a room? Divide the volume of the room by the fan's flow rate, using the same unit system. The volume unit will cancel out, leaving only the time unit. The number achieved here is the time it takes for the air in the space to be replaced ...
flow rate, and you can calculate how the rate will change when you change the radius. It's also possible to maintain the radius constant and vary the pipe length, although this would require a different constant. Comparing predicted to measured values of flow rate tells you how much ...
How to calculate vital capacity Vital Capacity:Vital capacity refers to the maximal volume of air that a person can blow out of their lungs following a maximal inhalation. For example, if you were to inhale as deeply as you could, then blow out as much air as you could, the amount of ...
To calculate the time it takes for the nylon to drop from 350 F to 100 F, you would need to calculate the rate of heat transfer between the two materials, and then divide the amount of energy needed to cool the nylon by the rate of heat transfer. You can then ...
