- The temperature of the ball as a function of time, T(t) in thebath may be estimated by this equation:T(t) = (Ti – T∞)e–t/τ + T ∞where t is the time in seconds in the bath; Ti is the initial ball temperature;T∞ is the oil temperature; and τ is the time constant in seconds thatdepends upon the material of the ball, the geometry of the ball, and oilproperties. Assume that the initial ball temperature = 800°C, the oil temperature = 40°C, and the time constant = 50 seconds. Using MATLAB, find the time at which the temperature of the ball bearing equals 600°C, 300°C, and 50°CFor supersonic and hypersonic wind tunnels, a diffuser efficiency, ηD,can be defined as the ratio of the total pressures at the diffuser exit andnozzle reservoir, divided by the total pressure ratio across a normal shockat the test-section Mach number. This is a measure of the efficiency ofthe diffuser relative to normal shock pressure recovery. Consider asupersonic wind tunnel designed for a test-section Mach number of 3.0which exhausts directly to the atmosphere. The diffuser efficiency is 1.2.Calculate the minimum reservoir pressure necessary for running thetunnel.A gasoline engine is at a location where the temperature is measured to be 14.8 °C and produces 300 kW at 5800 rpm while consuming 0.0184 kg/s of fuel. During operation, data shows that its mechanical energy loss is 18 %, the actual volume of air going into each cylinder is 80% (the volumetric efficiency has a negligible variation), and the actual fuel-to-air ratio is 0.065. What were the engine parameters at sea level conditions if the pressure here is 99.3 kPa and the temperature here is 18 0C hotter than that of the elevated condition? Determine at sea-level conditions the Brake Power in kW.
