Water at 20°C flows past a circular cylinder in cross-flow at a free stream velocity of 0.5 m/s. The cylinder is 0.02m in diameter and has a length of 0.5m in the cross-stream direction. The cylinder is at a temperature of 60°C. Find the rate at which heat is transferred from the cylinder.
Five pounds of propane have a volume of 1 ft3 and a pressure of 600 psi. Determine the temperature (in °R) using each of the following methods.
a balloon is to be filled from a helium tank. the tank is large and the tank pressure remains effectively constant
How the tensile stress and compressive stress result in the moment about neutral axis when the beam fails
Evaluate the statistical properties of a population of the nuts and evaluate the statistical properties of a sample of nuts to infer data about the entire population. Did the factory create all the nuts equally?
a 5-ft3 tank contains 0.6-gravity natural gas at 1500 psia and 100of. 200 scf of gas is released from the tank. this
given the velocity field v 10x2 y i 15 y z j - 3xy-25t k finda the acceleration of a fluid element at a point 12-1 at
The pressure gauge on a 2.5-m^3 oxygen tank reads 500 kPa. Determine the amount of oxygen in the tank if the temperature is 28 degrees C and the atmospheric pressure is 97 kPa.
Calculate the delta velocity required to change the inclination of a circular orbit at 32,000 km altitude from a 28.5 degree inclination to an inclination of 45 degrees. Compute the propellant used if the satellite weighs 1200 lbs after the maneuver.
the wheel of the slider-crank mechanism shown in the figure is rotating counterclockwise at a constant rate of 10 rads.
a grain dryer consists of a vertical cylindrical hopper through which hot air is blown. the air enters the base at 1.38
Refrigerant R134a is compressed under steady conditions from a saturated vapour at 100 kPa to 500 kPa. The compressor’s isentropic efficiency is 85%. Heat losses from the compressor can be ignored, as can kinetic energy and potential energy effects.
Deduce a set of boundary-layer differential equations (continuity, momentum, energy) for steady flow of a constant-property fluid without body forces, and with negligible viscous dissipation, in a coordinate system suitable for analysis of the bounda..
