Final answer:
The information given is insufficient to determine the exact length of piping required for the kitchen sink. For the questions about converting units and scaling recipes, elementary arithmetic conversions can be applied to obtain the answers.
Step-by-step explanation:
A plumber is fitting pipes for a remodeled kitchen sink. However, the information provided does not contain the necessary details about the lengths of the sections of piping required, making it impossible to accurately determine how many feet of piping is necessary. The proper length would depend on specific measurements given in a diagram or written instructions, which are not provided.
As for the question of the speed of water emerging from a pipe given a force on a plunger, we would employ Bernoulli's principle or other relevant fluid dynamics equations. However, without additional necessary details, such as the length of the pipe and the properties of the fluid, we cannot calculate the precise speed of water emerging from the pipe.
The conversion questions about the garden, such as converting yards to feet or inches and scaling down a recipe, are straightforward arithmetic problems. For instance, 1 yard is equal to 3 feet, so a garden that is 4 yards in length would be 12 feet long. Similarly, if the width of the garden is 4 yards, it would be 144 inches wide since there are 36 inches in a yard.
