21. "Atrato " s boilers had a working pressure of 150 trials and a service speed of. 22. Depending on engine speed, this pressure can easily reach up to 60 PSI maximum working pressure . 23. Also, a hydraulic motor is usually designed for working pressure at both sides of the motor. 24. Working conditions would be'850 / 850', with a working pressure of and a steam temperature of. 25. Each boiler had a capacity of 1, 000 horsepower and a working pressure of 200 psi. 26. This is because working pressure is directly proportional to wall thickness and inversely proportional to diameter. 27. Steam was provided by eight Kampon Type B water-tube boilers with a working pressure of at. 28. These provided a large steam space above the waterline, but their flat surfaces limited working pressure . 29. The ship had one two-cylinder horizontal boilers provided steam to the engine at a working pressure of. 30. Steam for these turbines was provided by nineteen Type B Kampon boilers with a working pressure of.
