Determine the air mass flow rate into the hair drier, in kg/s. Determine the air volume flow rate at the hair drier exit, in m3/s. Determine the diameter of the drier exit in mm.
Is acceleration constant throughout the jump? Also, recall from earlier that you must integrate if acceleration is a function of position. What maximum force does the cord exert on him?
The pipe carries oil, with a density of 850 kg/ m3, at a rate of 0.45 m3/sec. Compute the magnitude and direction of the force acting on the turn.
If the coefficient of friction between the 400 lb weight and the table is 0.25, determine the acceleration of the system and the tension in the cord.
If the inner surface temperature of the pipe is maintained at a constant temperature of 150c determine the temperature at The base flange and the rate of heat loss through the flange.
The electrical resistor transfers 95 Btu of energy into the system. Eventually the system comes to equilibrium. Determine the final equilibrium temperature, in °F.
A 9.0 ice cube at -30 is in a rigid, sealed container from which all the air has been evacuated. How much heat is required to change this ice cube into steam at 200 ?
The speed of the hawk relative to you is 1.59 m/s. What are (a) the magnitude and (b) direction of the hawk's velocity relative to the ground? Express the directional angle relative to due east.
