Schematic of one Vertical cuttings dryer. Figure 1. shows an example schematic for one typical horizontal dryer. Cuttings removed in the primary solids control section enter in the feed inlet. Processed cuttings are removed after the dryer removes oil (or NAF). The oil or NAF is recovered and returned to the drilling fluid system.

Vertical Cutting Dryer. Vertical Cutting Dryer makes use of a unique force to dry solids from oil and other base fluids. The steel vessel catches the wet solids due to its stainless nature. The dry wastes are removed by the angles attached to the machine that rotate slightly slower than the bowl whereas liquid is thrown out through the bowl openings.
Centrifugal pump specific speed is a crucial parameter used in the evaluation and selection of centrifugal pumps. It is a dimensionless number that provides valuable information about the performance characteristics of a pump. Specific speed is defined as the speed at which a geometrically similar pump would operate to deliver 1 unit of flow rate against 1 unit of head. Understanding the specific speed of a centrifugal pump is essential for engineers and designers in optimizing pump performance and efficiency.

Pump Specific Speed Chart
Specific speed is calculated using the formula:
\[ N_s = \dfrac{N \sqrt{Q}}{H^{3/4}} \]
Where:
- \( N_s \) = Specific speed
- \( N \) = Pump speed (rpm)
- \( Q \) = Flow rate (m\(^3\)/s)
- \( H \) = Total head (m)
Specific speed values can vary widely depending on the pump design and application. For centrifugal pumps, specific speed is typically categorized into three ranges:
1. Low Specific Speed (N_s < 500)
2. Medium Specific Speed (500 < N_s < 2500)
3. High Specific Speed (N_s > 2500)
Centrifugal Pump Efficiency Chart
Efficiency is a critical factor in the performance of centrifugal pumps. The efficiency of a pump is influenced by its specific speed, design, and operating conditions. A centrifugal pump efficiency chart provides a graphical representation of the relationship between flow rate, head, and efficiency for a specific pump.
Specific Speed of Pump Calculator
To calculate the specific speed of a centrifugal pump, you can use online calculators or software tools specifically designed for this purpose. These calculators require input parameters such as pump speed, flow rate, and total head to determine the specific speed of the pump.
How to Calculate Pump Speed
The speed of a pump is typically specified by the manufacturer and is an essential parameter for pump selection and operation. Pump speed can be calculated using the formula:
\[ N = \dfrac{120 \times f}{P} \]
Where:
- \( N \) = Pump speed (rpm)
- \( f \) = Frequency of power supply (Hz)
- \( P \) = Number of poles in the motor
Suction Specific Speed Calculator
Suction specific speed is another important parameter used in the evaluation of centrifugal pumps, especially for applications with high suction energy. The suction specific speed calculator helps determine the suction specific speed of a pump based on input parameters such as flow rate, suction head, and impeller diameter.
Specific Speed of Pump Definition
A pump has the capacity 1500 US gal/min (1249 British gpm, 340 m3/h, 5667 liters/min) at 100 ft(30.5 m) of head and is rotating at 1760 rev/min. See more
