Question

PI1105 worksheet 8 . Fluids, Oscillations nstructor Kaminski (2 pointa) 1.) Sinking car A car as a total mass of 1739 kg. The volume of air space in the passenger compartment 5.00 rear whoela, eas tank, and trunk is o.s00m Water cannot enter these two regions The volume of the motor and frout wheels is o 750 m", and the volume of the The car rolls into a lake. No water enters the pussenger compartment. How much of the car, in cubic meters, is below the water surface with the car flonting (2 pointa) 2.) Water fnow through varying pipes The water flowing through a 2.3 em (inside diameter) pipe flows out through three 1.1 em pipes (a) If the flow rates in the three smaller pipes are 27, 18, and 10 L/min, what is the flow rate in the 2.3 em pipe? (b) What is the ratio of the speed of water in the 2.3 cm pipe to that in the pipe carrying 27 L/min?

Explanation / Answer

Solving 1st question

We know,the car will float if weight of the car is balanced by the upthrust force of water

Upthrust force is given by

U=volume of fluid displaced*density of fluid*g

This must be equal to weight of car

1730*9.8=V*1000*9.8

We got V=1.73 cubic meter
