What is spanner size for Heavy Hex Stud and Nuts?

There are a lot of tables, but you can use formula of nominal stud diameter x 1.5 + 1/8 inch in most cases, for example a 1-1/2" stud uses a 2-3/8" wrench size.

How to find out length of holding tube in pasteurizer?

Pasteurization requires that the milk is in custody for a specified time. The appropriate length for the holding tube can be calculated by the flow rate (Q) of milk and the diameter (D) of the holding tube using the formula: Length of holding tube, L = Q x holding time/A x η A = Area = pi/4 x sqr D Where an efficiency factor, η, of 0.85 is used in the model.

Specific power consumption of Air compressor

Specific Power Consumption Specific power consumption is the ratio of the power consumed by an engine to a certain force such as the amount of output the engine (equipment) produces. It allows engines (equipments) of all different sizes to be compared to see which is the most power efficient. It allows manufacturers to see which engine (equipment) will use the least power while still producing a high amount of output. Specific power consumption of Air compressor The ratio of power consumption (in KW) to the volume delivered at ambient conditions. Specific power consumption= Actual power consumed by the compressor/Measured free air delivery If the measured flow is 250 m3/hr and actual power consumption is 30KW. Then Specific power requirement = 20 KW/250 m3/hr

How to find out Power input into the motor compressor?

Power input into the motor compressor is obtained by the following formula: Power Pcomp =M x (h2 - h1) Power Pcomp = Power input into the motor compressor M = The mass flow rate of the refrigerant h1 = Enthalpy at inlet to the process, h2 = Enthalpy at outlet to the process,
