Question:
At a fixed instrument location in levelling, if the backsight reading at a point P is more than the foresight reading at a point Q, then
At a fixed instrument location in levelling, if the backsight reading at a point P is more than the foresight reading at a point Q, then
Updated On: Jul 12, 2024
- point P has lower elevation than point Q
- point P has higher elevation than point Q
- the elevation difference between P and Q depends on height of the instrument
- the elevation difference between P and Q depends on benchmark elevation

- To finalize the direction of a survey, four surveyors set up a theodolite at a station P and performed all the temporary adjustments. From the station P, each of the surveyors observed the bearing to a tower located at station Q with the same instrument without shifting it. The bearings observed by the surveyors are 30° 30' 00", 30° 29′ 40′′, 30° 30′ 20′′ and 30° 31′ 20′′. Assuming that each measurement is taken with equal precision, the most probable value of the bearing is

- A 2m × 2m tank of 3 m height has inflow, outflow and stirring mechanisms. Initially, the tank was half-filled with fresh water. At t = 0, an inflow of a salt solution of concentration 5 g/m3 at the rate of 2 litre/s and an outflow of the well stirred mixture at the rate of 1 litre/s are initiated. This process can be modelled using the following differential equation:
\(\frac {dm}{dt}+\frac {m}{6000+t}=0.01\)
where m is the mass (grams) of the salt at time t (seconds). The mass of the salt (in grams) in the tank at 75% of its capacity is _____ (rounded off to 2 decimal places).- GATE CE - 2024
