Oil is flowing down a channel into a storage tank without splashing. The oil is flowing at a rate of 1200 kg/min1200\text{ kg/min}1200 kg/min. The length and width of the tank are 3.20 m3.20\text{ m}3.20 m and 1.50 m1.50\text{ m}1.50 m. The density of the oil is 800 kg/m3800\text{ kg/m}^3800 kg/m3.
Initially, the tank is empty. Calculate the depth of oil in the tank after 1.00 minute1.00\text{ minute}1.00 minute. Give your answer to three significant figures.
The height of the oil decreases by 0.600 m0.600\text{ m}0.600 m as it flows down the channel. Calculate the decrease in gravitational potential energy of the oil each second.
The oil stops flowing. The depth of oil in the tank is 1.10 m1.10\text{ m}1.10 m. Calculate the pressure at the bottom of the tank due to the oil.
