NPSH stands for Net Positive Suction Head and is a measure of the pressure available at the suction port of a pump to prevent cavitation.

• NPSH is important for ensuring that a pump does not cavitate, which can cause damage to the pump and reduce its efficiency.

• It is calculated by subtracting the vapor pressure of the liquid being pumped from the total suction head of the pump.

• NPSH is typically provided by the pump manufacturer and must be considered when designing a pumping sy...read more

PHE heat load can be calculated by considering the flow rate, specific heat capacity, and temperature difference of the fluids involved.

• Calculate the mass flow rate of the fluids passing through the Plate Heat Exchanger (PHE).

• Determine the specific heat capacity of the fluids.

• Find the temperature difference between the hot and cold fluids.

• Use the formula: Q = m * Cp * ΔT, where Q is the heat load, m is the mass flow rate, Cp is the specific heat capacity, and ΔT is the temper...read more
