Question
![A square bottomed tank measures 25*25*160cm
and is positioned with the bottom of the tank 1m
above sea level and at 20degreesC. The tank is
90% filled with water and 10% air. A water inlet
enters the centre of the tank of 10mm diameter,
and no other inlet or outlet is open within the
tank. A pump drives water at a starting rate of
450ml/min at 0 Pa lowering to 350ml/min as the
pressure increases to 800 kPa. The pump and
tank are connected by a 10mm diameter pipe
with k=0.15 for all fittings and tubing. It should
be assumed this is the maximum flow and
pressure provided by the pump. The pump will
stop instantaneously once the pressure reaches
800kPa. The relationship between flow and
pressure from the pump should be assumed
linear.
What will be the volume of compressed air
inside the tank and how long will it take to fill?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F04a04416-13a1-4937-9d96-c9549c8907df%2Fd41ed8d2-acac-4898-9edc-3ac61dc05ed9%2Fxpgd9qb_processed.png&w=3840&q=75)
