A storage tank holds 75 cubic meters of a gas at 28deg C and a pressure of 130kPa. The gas appears to have a molecular weight of 30 from tests run in a laboratory. Estimate the mass of the gas in the tank in kg assuming the gas behaves as an ideal gas. If the gas warms up to 35 deg C as it sits in the sun all day, what would the pressure rise to?
If the deflection of the gae fluid height, h, is 2 inches find the 1) velocity of the jet air and 2) the force exerted on the disk by the air.
Determine the Final Velocity, An object whose mass is 1 lb has a velocity of 100 ft/s. How would I determine the final velocity, in ft/s, if the kinetic energy of the object decreases
Motor M draws in the cable with an acceleration of 4 ft/s2, measured relative to the 200-lb mine car. Determine the acceleration of the car and the tension in the cable. Neglect the mass of the pulleys.
A trapezoidal channel made out of brick, with bottom width 6ft and with bottom slope 0.001
Define your system to be the gas in the cylinder, and calculate the work transferred from the surroundings to the system from this expansion. Note that the pressure will change as the expansion takes place.
the motion of the slender 10kg rod AB is guided by collars of negligible mass that slide freely on the vertical and horizontal rods. knowing that the bar is released from rest when θ=30, determine the velocity of the collars A and B when θ = 60.
An air bubble rises from the bottom of a well where the temperature is 25°C, to the surface where the temperature is 27°C. Find the percent increase in the volume of the bubble if the depth of the well is 5 m. Atmospheric pressure is 101,528 Pasca..
a reactor setpoint wasincreased from 160 psig to 190 psig. the reactor pressure transmitter was recalibrated from 0-200 psig to 0-300 psig. what is the percent span for the old and new setpoints?
Find the corresponding damping coefficient c. Identify the system parameters such as the natural frequency and damped frequency. Derive the mathematical expression of the displacement as a function of time with the given initial condition. Plot yo..
