Stop cooling-water flow in turbine
Whether you stop cooling-water flow through steam condenser when the turbine is slopped?
Expert
You must keep circulate the cooling water for 15 mill or more, so that the condenser has chance to cool down. Ensure to have cooling water flowing through condenser before starting up to prevent the live steam from entering the condenser until it gets cooled. Overheating may cause various leaks and other headaches.
Air at 20 m/s, 260 K, 75 kPa with 5 kg/s flows into a jet engine and it flows out at 500 m/s, 800 K, 75 kPa. What is the change (power) in flow of kinetic energy?
Draw a frequency-response curves for a damped single degree of freedom system subjected to a harmonic excitation under three different damping ratios. System has a natural frequency of ωn as the forcing frequency of the excitation is ω. Describe
The approximate equation for the velocity distribution in a rectangular channel with the turbulent flow is Q : Size and weight in Product design Size and weight: If the product is particularly small the cost may be increased if more precise manufacturing methods are demanded.
