Solve the following problems given below:
Problem I: Find the average molecular weight and specific gas constant for moist air saturated with water vapor at 0 degrees Celsius and 1000hPa of total pressure. Then determine the virtual temperature, density (rho), mixing ratio w, water vapor density (=absolute humidity) (rho sub v). The saturation vapor pressure of water at 0 degrees Celsius is 6.11 hPa.
Problem II: By what percentage is the density rho greater or less than that for dry air at the same pressure and temperature?
I need help to find the average molecular weight and specific gas constant.
A wagon is rolling forward on level ground. Friction is negligible.The person sitting in the wagon is holding a rock. The total mass of the wagon, rider, and rock is 91 kg. The mass of the rock is0.30 kg.
question what is the minimum amount of electrical energy required by the refrigerator to carry out this process if it
Two blocks with masses m = 16.7 kg and M = 70.1 kg are not attached. The coefficient of static friction between the blocks is 0.45 but the surface beneath M is frictionless. What is the minimum force F required to hold m against M?
use the inverse square law to display that in space shuttle territory, 200 kilometers above earth's surface, the force of gravity on a shuttle is about 94 percent of that at earth's surface.
A He-Ne laser produces light of wavelength 633 nm with intensity 1.02 103 W/m2, over a beam of cross-sectional area 0.940 mm2. How many photons per second are emitted by the laser?
A car rounds a 230 m -radius curve at 14.5 m/s. If the horizontal force acting on the car is 790 N, what's the car's mass
What should the charge (sign and magnitude) of a particle of mass 1.21 be for it to remain stationary when placed in a downward-directed electric field of magnitude 610.
A box with a mass of 8 kg is lifted (without acceleration) through a height of 9 m, in order to place it upon the shelf of the closet.
A baton twirler throws a spinning baton directly upward. As it goes up and returns to the twirler's hand, the baton turns during 5.53 revolutions. Ignoring air resistance and assuming that the average angular speed of the baton is 2.21 rev/s, decide ..
A 4 kg mass is connected to a spring (k = 730 N/m) platform which undergoes simple harmonic motion in the vertical direction. The amplitude of the oscillation is 5 cm. At t=0 the box is 5 cm above the equilibrium position.
A 6.0 cm diameter horizontal pipe gradually narrows to 4.0cm. When water flows through the pipe at a certain rate, the gauge pressure in these two sections is 32.0 kPA and 24.0 kPA respectively. What is the volume rate of flow?
