Benson (once-through, supercritical) boiler: typical steaming capacity. Choose the approximate rate of steam production commonly associated with Benson boilers in standard references and exam data.

Difficulty: Easy

100 tonnes/h
135 tonnes/h
175 tonnes/h
250 tonnes/h

Correct Answer: 135 tonnes/h

Explanation:

Concept
The Benson boiler is a once-through, high-pressure (often supercritical) water-tube boiler. Standard objective-type references commonly quote a typical steaming capacity around 135 tonnes per hour for benchmark problems.

Notes
Although practical designs may span a wide range, 135 t/h is the widely accepted figure for textbook MCQs.

Final Answer
135 tonnes/h

Benson boiler: average operating pressure range and representative value. Select the most commonly cited average operating pressure for a Benson boiler used in exam practice (options in bar).
Natural draught definition: verify the correctness of the statement. Statement: A draught produced by a chimney due to the density difference between hot gases inside the chimney and the colder outside air is called natural draught. Choose the correct option (True/False).
Aim of compounding in steam engines: identify the principal objective(s). Compounding splits the total expansion across multiple cylinders (HP→IP→LP) to improve performance. Choose the best statement describing the aim.
Loeffler boiler classification: verify the circulation method. Statement: The Loeffler boiler is a water-tube boiler that uses forced circulation of water/steam to avoid salt deposition in evaporator tubes. Choose the correct option (True/False).
Crosshead function in a reciprocating steam engine: fill in the missing part correctly. The function of a crosshead is to guide the motion of the __________ and prevent it from bending, while transmitting force to the connecting rod. Choose the correct completion.
Piston rod function: identify the correct role in a reciprocating steam engine. Select the statement that correctly describes the function of a piston rod.
Locomotive boiler dimensions: select the typical length of the boiler shell (approximate). Choose the most commonly cited shell length among the options provided.
Boilers classification: identify the correct combined statement about common boiler types Check each named boiler against its family (fire-tube or water-tube) and firing arrangement. Choose the correct option.
Steam engines: effect of wire drawing (throttling during valve events) on the indicator diagram and work done Assess whether throttling (wire drawing) reduces the diagram area and thus the indicated work of the engine. State whether the statement is true or false.
Reciprocating steam engine: conversion of steam's thermal energy into mechanical work Confirm the basic working principle — heat in steam is converted into piston reciprocation and then shaft work. State whether the statement is true or false.
