Extensive testing of an experimental 2820-lb automobile reveals the aerodynamic drag force FD and the total no aerodynamic rolling-resistance force FR to be as shown in the plot. Determine (a) the power required for steady speeds of 22 and 44 mi/hr o..
At one section in an air distribution system, air at 14.7 psi and 100degree F has a velocity of 1200 ft/min a and the duct is 12 in x12 in square. At another section the duct is round with a diameter of 18 inches and the velocity is 900 ft/min. Calcu..
A rock weighs 90.8 N in air and 45 N when completely submerged in water. Determine the specific volume of the rock in m3/kg
A turbine extracts energy from water flowing through a 11-cm-diameter pipe at a pressure of 700 kPa with an average velocity of 11 m/s. If the turbine is 90 percent efficient, how much energy can be produced if the water is emitted from the turbine t..
1750g of air performs an expansion work of 3100kJ on the surrounding as it expands isothermally to a pressure of 63000kPa ad a volume of 0.065 cubic meters. Determine the temperature of the air and the initial volume.
In a polytropic process, a fluid is compressed to 2.75 times its initial pressure, whereas its temperature becomes1.65 times. What is the fluids index of expansion, n? 1.2kg of Air at a pressure of 2.15MPa and a temperature of 585K, undergoes a rever..
Air exerts a pressure of 900KPa within a 0.45 cubic meter container of fixed volume. It is cooled such that the pressure falls to 3.25bar. The temperature of the air is then measured and was found to be 285C. Determine the mass of the air, the initia..
Air enters a gas turbine with a velocity of 165m/s and a specific enthalphy of 2800KJ/kg and leaves with a velocity of 135m/s and specific enthalpy of 2175KJ/kg. The heat lost to the surrounding turbine is 32.5KJ/kg. Determine power developed by the ..
Liquid water in a pumped flow system experiences varying pressures as it circulates through the system. One concern in designing any such system is to ensure that cavitation does not occur. If the water temperature during operation of a particular sy..
What is the difference between mixed and unmixed flow in heat exchangers?
SEM212 - Aim of this demonstration is to use measurements of the load required to propagate a crack (tear) in packaging tape to determine its fracture toughness.
determine the time it takes for the ball to start rolling without slip and its speed when it does so. In addition, determine the distance it travels before it starts rolling without slip. Assume (mu)K = 0.10.
