Absolute pressure at the bottom of the lake = pressure due to water height + Air pressure = Density of water*gravitational acceleration* height + 101.3 kPa
Therefore,
Absolute pressure = 1/1000(1*10^3*9.81*29.1) + 101.3 = 285.471+101.3 = 386.771 kPa
Answer:
The people with caculators will probably answer faster due to thier ablitiy to use a device of technology
