1.A glass jar is heated in an oven and sealed when the air pressure is 103 kPa and the temperature is 105 C. Find the absolute, gage, and vacuum pressures in the jar when it cools to 20 C. Find the absolute, gage, and vacuum pressure heads in meters of 20 C water
2.A wave has a height of 1.5 m in water 5 m deep and a wave period of 6 s. Plot the horizontal component of velocity, the vertical component of acceleration, and the dynamic pressure at a point 2 m below the still water level versus time for a 6-s interval. Plot the three values on the same diagram and comment on the results.
The pressure on the back side is negative; its magnitude is 0.5 times the (negative) stagnation pressure on the back side. Determine the drag coefficient for the sign type
a particle travels along a straight line with anbspvelocity v 12-3t2 ms where t is in seconds.nbspwhen t 1 s the
The variation in the diffusion coefficient with temperature, over an appropriate range of temperature, can usually be approximated as follows: D= (D0)e^-(Q/(KT) where, Q = activation energy (eV/atom) and k = Boltzmann's constant (8.616*10-5 eV/ato..
You have a steel alloy with a 1.00 wt% carbon content that is cooled to room temperature. What is the eutectoid cementite content of this sample
the pin at B is attached to member ABC and can slide freely along the slot cut in the fixed plate. Neglecting the effect of friction, determine the couple M required to hold the system in equilibrium when.
For a temperature of 10 degree C, calculate the time needed for the following particles to settle 0.3m: a) a 20um mineral particle with a specific gravity of 2.1, and b) a 2 um organic particle with a specific gravity of 1.2
Using Raoult's Law or Henry's Law, as appropriate, calculate the pressure and mole fractions in the vapor phase for a system containing a liquid that is 0.3% N2 and 99.7% water (by moles) in equilibrium with its vapor at 80 °C.
How many cubic yards of aggregate must be ordered for a road base 16 inches thick and 2000 feet long with a top width of 30 ft, if the side slopes are one on one, or 45 degree?
Discharge from an orifice of 75mm diameter is 0.02 m^3/s under a constant head of 3 m. An external mouthpiece of the same diameter is installed that raises the coefficient of contraction from 0.63 to 1.0.
How much differential settlement is causing the additional stress of 4,000 psi in girder that is rigudly attached to columns at either end of its 50-ft span. The moment of inertia of the beam is 15,000 in4, and it is a 24-in.-deep beam section.
Describe a piece of John Deere agricultural equipment that utilizes GPS hardware and software. Describe how many RECs are placed on the equipment and where it is placed.
