Given below are two statements:
Statement (I): Low salinity water can be used for irrigation with most crops and most soils. But some leaching is required.
Statement (II): Medium salinity water can be used with crops that can tolerate moderate salinity and leaching. But high salinity water is not ordinarily suitable for irrigation but to be used under special conditions with good drainage and with salt tolerant crops.
In light of the above statements, choose the most appropriate answer from the options given below:
The drawbacks of Thornthwaite formula as enumerated by Chang (1968) are: (A). Air humidity alone is a good indication for the energy available for ET., (B). Air temperature at a place lags behind radiation., (C). According to formula ET will cease when mean temperature is below 0 degree C which by no means is true., (D).The formula does not take into account the wind effect which might be an important factor in some areas., (E). It considers the effect of warm and cool air on the temperature of a place. Choose the correct answer from the options given below:
A four cylinder 4-stroke gas engine has cylinder diameter of 20 cm, stroke-bore ratio is 1.5; clearance volume \(2500 \text{ cm}^3\), engine speed 300 RPM, mean effective pressure \(5 \text{ kg}\cdot\text{cm}^{-2}\) and mechanical efficiency 70 per cent. Calculate IHP of the engine in kW.
The best measure of central tendency and dispersion are respectively
The mean, median and mode for the data (5, 6, 9, 3, 2, 5, 8, 1, 7, 4) is
