Consider supersonic flow of air through a 6-cmdiameter duct with negligible friction. Air enters the duct at Ma1 =1.8, P01 =210 kPa, and T01 =600 K, and it is decelerated by heating. Determine the highest temperature that air can be heated by heat addition while the mass flow rate remains constant.
Offshore oil exploration platform is expected to encounter current of 3 m/s wave height 4 m and periods 15 seconds. A 1 in 20 scale modes is to be build and tested in hydraulic laboratory to determine the forces on the full scale structure.
Solubility of a substance which dissolves with an increase in volume and liberation of heat will be favoured by the A. low pressure and high temperature. B. low pressure and low temperature. C. high pressure and low temperature. D. high pressure and ..
Air (m=28.97kg/kmol) is uniformly heated at steady state as it flows through a cylindrical constant area duct. It enters the channel uniformly at 2.5atm, 300K and 80m/s and exits at 1.5atm.
Use the Bernoulli equation to describe how this manometer can be used to measure the flow rate through the meter.
Two new rides are being compared by a local amusement park in terms of their annual operating costs. The two rides are assumed to be able to generate the same level of revenue (and thus the focus on costs). The Tummy Tugger has fixed costs of $10,000..
The forward direction is given by the alphabeteical order of the station names. Each angle is measured clockwise from the back direction to the forward direction so that they are on the left of the traverse looking forward.
a police officer stops a speeding driver on saturday nigt and gives hima breathalzer test. the test shows that his estimated blood alcohol content is above .08 g/dl, and this is considered evidence of driving while intoxicated
A cyclone is designed with an inlet width (W) of 12.0 cm and has four effective turns. The inlet gas velocity is 15.0 m/s and the particle density is 1.70 g/cm3. (a) Estimate the particle size that will be collected with 50 % efficiency.
Determine the power input to the heat pump and the electric power saved by using a heat pump instead of a resistance heater.
