Q2. Cooling tower capacity
Ans. 
Cooling tower capacity is the maximum amount of heat that can be removed by the tower in a given time period.
• Cooling tower capacity is typically measured in tons of refrigeration or kilowatts.

• Factors affecting cooling tower capacity include design temperature range, flow rate, and wet bulb temperature.

• Cooling tower capacity can be calculated using the formula: Q = mcΔT, where Q is the heat load, m is the flow rate of t...read more

Q2. Why Ssc is increased when load is reduced As a dcs engineer what should you do if vacuum is decreasing continuesly what are the turbine bearings temperatures running on full load alarms and trippings ...read more
Ans. 
SSC increases when load is reduced due to increased reactive power. Decreasing vacuum may indicate a leak or malfunction. Turbine bearing temperatures and alarms/trippings values depend on specific turbine model and operating conditions.
• SSC (Synchronous Condenser Capacity) increases when load is reduced due to increased reactive power.

• Decreasing vacuum may indicate a leak or malfunction in the system. As a DCS engineer...read more
