A horizontal, 25-mm diameter cylinder is maintained at a uniform surface temperature of 35°C. A fluid with a velocity of 0.05 m/s and temperature of 20°C is in cross flow over the cylinder. Determine whether heat transfer by free convection will be significant for
(i) air,
(ii) water,
(iii) engine oil, and
(iv) mercury.
Suppose that you start with 103 g of a pure radioactive substance and 2 h later determine that only 0:25 103 g of the substance remains. What is the half-life of this substance?
explain how a supercritical flow changes to a subcritical flow. You may need to refer text books and web pages to answer this question.
Van Laar equation to calculate activity coefficients, How do I use the Van Laar equation to calculate an activity coefficient for an equilibrium ethanol/water binary system with mole fractions of ethanol in liquid of
Select a process variable (pressure / temperature / level / flow) and conduct a literature survey to determine recent developments in process instrumentation field. Identify any one novel instrument and explain in detail the working of the instrument..
There are four stable isotopes of iron with mass numbers 54, 56, 57, and 58. There are also two radioactive isotopes: iron-53 and iron- 59. Predict modes of decay for these two isotopes. (See Table 18.2.).
Determine the voltage transfer function of the low pass filter circuit shown in Figure P3.4.6, and find the expression for ω0.
One type of commercial smoke detector contains a minute amount of radioactive americium-241 (241Am), which decays by -particle production. The particles ionize molecules in the air, allowing it to conduct an electric current. When smoke particle..
The two hoops are kept parallel to each other and rotate at 600 rpm in a constant magnetic field as shown in Figure 10.41. Calculate the potential difference between the two hoops.
Operation of a modern telephone handset, In a modern telephone handset, the microphone uses a piezo-electric crystal and the earpiece is a miniature loud speaker using a moving coil and a permanent magnet.
Suppose that participant 5 shows his share (5, 3). Why is one of these five people lying? Let all also participants 1 and 8 contribute there share: (2, 4) and (8, 12). Determine the liar and the real secret.
For a certain process, the maximum allowable pressure is 0.20 torr. If a D65 rotary vane pump is used and conductance losses in the vacuum system can be ignored; what is the maximum permissible inlet flow in standard cubic centimeters per minute?
PART - A . Using the following data, draw up a heat balance for a steel ingot soaking pit for a twenty hours test period during which 130 tons of cold steel ingots were heated from 20 oc to 1220oc.
