World Bank has employed major dimensions to construct measures of governance. These dimensions are:
1. Voice and Accountability - measuring political, civil and human rights
2. Instability an d violence - measuring the likelihood of violent threats to or changes in government, including terrorism
3. Government effectiveness - measuring the competence of the bureaucracy and the quality of public service delivery
4. Regulatory burden - measuring the incidence of market, unfriendly policies
5. Rule of law - measuring the quality of contract enforcement, the police, and the courts, as well as the likelihood of crime and violence
Select the correct answer:
Equilibrium moisture of a solid is equal to the total moisture minus free moisture. Which of the following substances will have maxi-mum equilibrium moisture?
Equilibrium moisture of a solid is equal to the total moisture minus free moisture. Which of the following substances will have maximum equilibrium moisture?
200 kg of solids (on dry basis) is subjected to a drying process for a period of 5000 seconds. The drying occurs in the constant rate period with the drying rate as, Nc = 0.5 × 10-3 kg/m2.s. The initial moisture content of the solid is 0.2 kg moisture/kg dry solid. The interfacial area available for drying is 4 m2/1000 kg of dry solid. The moisture content at the end of the drying period is (in kg moisture/kg dry solid)
A solid is being dried in the linear drying rate regime from moisture content Xo to XF. The drying rate is zero at X = 0 and the critical moisture content is the same as the initial moisture Xo. The drying time for M = (Ls/ARc) is (where, L = total mass of dry solid, A = total surface area for drying Rc = Constant maximum drying rate per unit area X = moisture content (in mass of water/mass of dry solids)
It takes 6 hours to dry a wet solid from 50% moisture content to the critical moisture content of 15%. How much longer it will take to dry the solid to 10% moisture content, under the same drying conditions? (The equilibrium moisture content of the solid is 5%).
In the following question, two columns are given containing three phrases each. The phrases are labelled A, B, and C in the first column and D, E and F in the second column. A phrase from the first column may or may not connect with a phrase in the second column to make a grammatically and contextually meaningful sentence. Identify the correct option from those given below that gives the correct sequence in which one or more sentences can be formed. If none of the options makes it possible for a meaningful sentence to be formed, indicate 'No of these' as your answer. Column 1 Column 2 A. A new technology developed by Indian scientists for ecological restoration is helping  D. could sense light, moisture, gravity, pressure and possessed several other qualities B. As early as in 1880, Charles Darwin demonstrated that plants  E. moisture contrasts known as weather fronts C. The major cause of rain production is moisture moving along three-dimensional zones of temperature and  F. in revival of mangroves degraded due to rising sea levels.  
A dryer is used for drying pears which has initial moisture content of 70 % (wet basis) and final moisture content of 5 % (wet basis). An experimental drying curve for the product indicates that the critical moisture content is 25 % (wet basis) and the time for constant drying is 5 min. Can you estimate the total drying time for product?
In a laboratory test run, the rate of drying was found to be 0.5 × 10-3 kg/m2.s, when the moisture content reduced from 0.4 to 0.1 on dry basis. The critical moisture content of the material is 0.08 on a dry basis. A tray dryer is used to dry 100 kg (dry basis) of the same material under identical conditions. The surface area of the material is 0.04 m2/kg of dry solid. The time required (in seconds) to reduce the moisture content of the solids from 0.3 to 0.2 (dry basis) is
