A concentrated solar power (CSP) plant uses a thermal storage system containing molten salt.
Write down the equation which links density (ρ\rhoρ), mass (mmm), and volume (VVV).
The thermal storage system contains a tank with 12,500 m312,500\text{ m}^312,500 m3 of molten salt. The density of the molten salt is 1980 kg/m3. Calculate the mass of molten salt in the tank. Give your answer in standard form.
Write down the equation which links energy transferred (EEE), power (PPP), and time (ttt).
The storage system can discharge thermal power to the steam turbines at a rate of 2.4 × 108 W for a maximum duration of 15 hours15\text{ hours}15 hours. Calculate the maximum energy transferred during this period. Give your answer in standard form.
