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?
To determine the heat transfer characteristics of a cylinder under cross flow conditions when the cylinder is isolated.
the 50-kg homogeneous smooth sphere rest on the 30 degree incline A and bears against the smooth vertical wall B. calculate the contact forces at A and B.
A linear isotropic material has the shear modulus of elasticity G of 11.5*10^6 psi and the Poisson's constant v of 0.3.
the entire assembly is placed in an environment whose temperature is 200c. determine the volume of chamber 1 when thermodynamic equillibrium has been estabilished.
Explain what is meant by an overall heat transfer coefficient and explain what is mean by failing and what its effect will be on the value of the overall heat transfer coefficient.
a standard steel specimen of 13 mm diameter elongated 22 mm when it was subjected to a tensile force of 29.5 kN if the specimen has a length of 200 mm and that force applied within elastic range. what is the elastic modulus of elasticity ?
To Verify the law for parallelogram of forces, law for triangle of forces and law of polygon of forces. These laws are very useful to calculate unknown forces in very short time.
