Which phenomenon reduces hydraulic pump efficiency during startup?

💡 Explanation

Increased viscous drag arises during hydraulic pump startup because lower fluid temperature, acting via Arrhenius relation, increases oil viscosity; therefore, viscous losses increase, rather than bulk modulus reducing flow or cavitation creating vapor bubbles.
