It is a common trick to fill a straw with water, put your finger on the top of straw, and then watch as the water is suspended within the straw.

Assuming that water has a density of 1000 kg/m^3 and the atmospheric pressure is 101 kPa, then estimate the pressure (kPa) of the air inside of the straw at the top of water column. Neglect any surface tension effects.

The driving force for fluid flow is the pressure difference, and a pump operates by raising the pressure of a fluid (by converting the mechanical shaft work to flow energy). A gasoline pump is measured to consume 3.8 kW of electric power when operating. If the pressure differential between the outlet and inlet of the pump is measured to be 7 kPa and the changes in velocity and elevation are negligible, determine the maximum possible volume flow rate of gasoline.

6.17 (Even or Odd) Write a method isEven that uses the remainder operator (%) to determine whether an integer is even. The method should take an integer argument and return true if the integer is even and false otherwise. Incorporate this method into an application that inputs a sequence of integers (one at a time) and determines whether each is even or odd.

Based on experimental observations, the acceleration of a particle is defined by the relationa = - (0.1 + sin (x/b)), where a and x are expressed in m/s^2 and meters, respectively. Knowing that b = 0.8 m and that v = 1 m/s when x = 0, determine (a) the velocity of the particle when x = - 1 m, (b) the position where the velocity is maximum, (c) the maximum velocity.
