Liquid propane is commonly used as a fuel for heating homes, powering vehicles such as forklifts, and filling portable picnic tanks. Consider a propane tank that initially contains 5ml of liquid propane at the environment temperature of 20 Celsius. If a hole develops in the connecting tube of a propane tank and propane starts to leak out, determine the temperature of propane when the pressure in the tank drops to 1 atm. Also determine the total amount of heat transfer from the environment to the tank to vaporize the entire propane in the tank.
The roadway to be constructed is 3 miles long and 60 feet wide. • The following pavement design specifications have been issued: - Base coarse: 6" DGA - Stabilized base: 4" - Bottom coarse of asphalt: 3" - Top coarse of asphalt: 2"
Given the following data for an undisturbed soil sample: Gs = 2.69, e = 0.65, water content = 10% Determine wet unit weight and dry unit weight, wet and dry density

Consider a velocity field V = axiˆ + by(1+ ct) ˆj , where a=b=2 sec-1, and c=0.4sec-1. For the particle that passes through the point (x,y)=(1,1) at the instant t=0, plot the pathline during the interval from t=0 to 1.5 sec.
an insulated tank is evacuated. Air from the atmosphere at 12 psia and 70 degrees farenheight is allowed to flow into the 100 cubic foot tank. What is the final temp and the final mass of air in the tank just after flow ceases.
An open channel with a trapezoidal configuration with side batters 1V:3H is to be designed to carry 1.0m^3/s with a bedslope of 0.0065. The channel is lined with concrete with manning's n of 0.011.
