Hardgrove Grindability Indices indicate that how hard the the coal is. The variation of HGI of each zone of 40 -60 means that the grindability is poor. Measurement of abrasivity (Yancey, Gear and Price method - YGP) is carried out on a limited number of samples in th literature. It,Comparison of Percentage Weight Loss and Corrosion,The simplest way of measuring the corrosion rate of a metal is to expose the sample to the test medium (e.g. sea water) and measure the loss of weight of the material as a function of time. Relative to metal density, exposed surface area, duration of exposure and some constant, the rate of corrosion of metal can be determined. Corrosion rate (CR), helps in understanding theWorking with lossy modes and dB/m to, - Lumerical,This means that any mode in the ridge waveguide that has an effective index greater than 3.475089 is bound (others will all leak away as slab modes).

Q.1: Determine the total heat loss from the building whose area is 60 sq. m, the coefficient of heat transfer is 0.7 and the temperature difference is 25 ∘ C. Solution: Given, U = 0.7; A = 60 \(\Delta t = 25C\) Substitute these values in the given formula, \(q = (U × A) × \Delta t\) q = 0.7 x 60 x 25. Therefore, q = 1050 watts. Q.2. Determine
