Flow rate to capacity
WebJul 22, 2024 · Metric units: The water flow rate of chilled water into the evaporator is 0.0995m3/s, the inlet temperature is 12*c and the outlet temperature is 6*c. This means the average temperature is 9*c so we lookup the water properties at this temperature to find the density of 999.78kg/m3 and a specific heat capacity of 4.19kJ/kg/K. WebFrom the temperature data logger, the chilled water supply and return temperatures and flow rate are as follow: Using the heat transfer formula in the SI unit, the chiller capacity can be calculated as follow: Q = ρVcθ Q = (1000) (172.75/3600) (4.2) (11.69-8.16) Q = 711.44 kW Q = 711.44 ÷ 3.52 Q = 202 TR

Q=Av Q = Av. where Q is the flow rate, A is the cross-sectional area at a point in the path of the flow and v is the velocity of the liquid at that point. In some situations, such as that of water flowing in a riverbed, calculating A is difficult, and the best you can do is an approximation. In others ...
WebValve Flow Coefficient (Cv) is a valve’s capacity for a liquid or gas to flow through it. It is technically defined as “the volume of water at 60°F (in US gallons) that will flow through a valve per minute with a pressure drop of 1 psi across the valve.”. In simpler terms, the larger the opening in a valve, the larger the Cv. WebThe Prinsco Drainage Calculator estimates the capacity of tile drainage systems.
