Question 43

Medium

A high-performance supercomputing facility requires a continuous electrical supply to run complex climate simulations.

Write down the equation which links energy transferred ( $E$ ), power ( $P$ ), and time ( $t$ ).

[1]

This supercomputing facility has a steady power consumption of $MW350\text{ MW}$ . Calculate the total energy consumed by the facility in a continuous period of $hours6.0\text{ hours}$ . Give your answer in joules ( $J\text{J}$ ) in scientific notation (standard form).

[3]

In a standard year of $days365\text{ days}$ , the supercomputing facility operated at its peak consumption for $76%76\%$ of the year. Calculate the number of days during that year that the facility operated at peak consumption. Give your answer to the nearest whole day.
