- Question 5 of 15
In a tray drying under adiabatic process, hot air enters the dryer at 50 Celsius dry bulb temperature (DBT) and 10% relative humidity (RH) with enthalpy of 70.2 kJ per kg dry air. The air leaving the dryer gains 20% moisture. Considering saturated water vapour pressure as 12.349 kPa at 50 Celsius DBT, the enthalpy of air leaving the dryer in kJ per kg dry air isCorrectIncorrect
- Question 6 of 15
A four-wheel-drive tractor has a static weight of 50 kN with 40% weight on rear axle and 60% on front axle. The wheel base is 2 m. The tractor is pulling a disc harrow that exerts a level drawbar pull at a hitch height of 0.5 m from the ground. During the operation, when the dynamic reaction on
each axle is same, the dynamic traction ratio developed by the tractor isCorrectIncorrect
- Question 7 of 15

- Question 8 of 15
A tractor gear box has 8 forward speeds. The speed ratios (number of engine revolutions for one revolution of driving wheel) vary in exact geometrical progression. If the speed ratios in highest and lowest gears are 14.9 and 108.8, respectively, the geometric constant isCorrectIncorrect
- Question 9 of 15
A multi-disc clutch has 4 steel discs and 3 bronze discs. The outside and inside diameters of contact surfaces are 250 mm and 180 mm, respectively. The coefficient of friction is 0.3 and axial force is 400 N. Assuming uniform wear, the power in kW that the clutch can transmit at 1000 rpm isCorrectIncorrect
- Question 10 of 15
A cultivator with a working width of 1.2 m utilizes 95% of its width due to overlapping while operating at a forward speed of 2 km/h. If the time lost in turning and other interruptions is 50 minutes per hectare, the field efficiency of the cultivator in percent isCorrectIncorrect
- Question 11 of 15
A two-row horizontal plate potato planter with 0.6 m ridge spacing has 9 cups on each seed plate of 0.4 m diameter. For each revolution of the ground wheel, the seed plate makes half a revolution.The diameter of the ground wheel is 0.5 m. If the planter uses cut tubers each of 25 g mass, the seed rate in kg/ha isCorrectIncorrect
- Question 12 of 15
A 200 m long horizontal pipe carries a discharge of 50 L/s. The centre line of the pipe is 5 m above the datum. The diameter of the pipe tapers from 200 mm to 100 mm. Using g = 9.81 m s–2 and neglecting losses in the pipe, if the pressure at the larger end of the pipe is 100 kPa, the pressure at the other end of the pipe in kPa isCorrectIncorrect
