Using the results of Prob. 8.47, determine the true metal temperature when the pyrometer indicates 450?C and the uncertainty in this temperature.
Prob. 8.47
The radiation from a metal part is measured with a pyrometer which indicates a temperature of 300?C. The actual part temperature is measured with a thermocouple which indicates 315?C. Both measurements have an uncertainty of ±1?C. From these measurements, determine the emissivity of the metal part and its uncertainty.
Concept of CSTR, A lagoon is to be designed to accommodate an input flow of 0.10 m^3/s of nonconservative pollutant with concentration 30.0mg/L and reaction rate 0.20/day
Calculate the Euler buckling load for a mild steel rod of length 5m and diameter 25mm when pinned at each end and axially loaded. If this rod is to be used again with an initially straight axis, determine the maximum permissible

A refrigerator uses carbon dioxide that is brought from 1 MPa, -20?C to 6 MPa using 2 kW power input to the compressor with a flow rate of 0.02 kg/s. Find the compressor exit temperature and its isentropic efficiency.
Consider a 300 kJ/min refrigeration system that operates on an ideal vapor-compression refrigeration cycle with refrigerant-134a as the working fluid.
A circular bar AB with ends fixed against rotation has a hole extending for half of its length (see figure). The outer diameter of the bar is d2 3.0 in. and the diameter of the hole is d1 2.4 in.
Describe in your own words the three strengthening mechanisms i.e., grain size reduction, solid solution strengthening, and strain hardening. Be sure to explain how dislocations are involved in each of the strengthening techniques.
Explain construction project and construction Project stages in details?
Laboratory clean rooms are often kept at a slightly higher pressure than ambient pressure in order to flush out particulates and keep dust from getting in. If the pressure in such a room is equivalent to 1 mm water greater than the surrounding roo..
