Aflat plate of width 1 m and length 0.2 m is maintained at a temperature of 32°c. ambient fluid at 22°c flows across the top of the plate in parallel flow. determine the average heat transfer coefficient, the convection heat transfer rate from the top of the plate, and the drag force on the plate for the following:

(a) the fluid is water flowing at a velocity of 0.5 m/s.
(b) the nanofluid of example 2.2 is flowing at a velocity of 0.5 m/s.
(c) water is flowing at a velocity of 2.5 m/s.
(d) the nanofluid of example 2.2 is flowing at a velocity of 2.5 m/s.

Aforce of 9.00 newtons acts at an angle of 19.0 to the horizontal. what is its component in the horizontal direction?

Which of the following is an example of units for speed

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
