Question

In a horizontal pipe carrying a smoothly flowing liquid with a density of 1370 kg/m^3, what is the pressure difference?

a) Depends on pipe diameter
b) 1370 Pa
c) Not enough information provided
d) Depends on liquid viscosity

Answer 1

The question does not provide enough information to determine the pressure difference in the pipe; it could depend on multiple factors such as pipe diameter, flow velocity, and fluid viscosity.

Step-by-step explanation:

The question is asking about the factors affecting the pressure difference in a flowing liquid within a horizontal pipe.

To answer this question, not enough information is provided.

The pressure difference in a flowing liquid can depend on several factors such as the pipe diameter, the velocity of fluid flow, the density of the fluid, and possibly the viscosity if the flow is not ideal.

The pressure difference can't be determined solely based on the density of the liquid.

Answer 2

Calculating the pressure difference in a horizontally flowing pipe requires additional details such as fluid velocity, pipe diameter, length, and potential energy changes, none of which are provided in the given question.c) Not enough information provided. The correct answer is c) Not enough information provided.

Step-by-step explanation:

The pressure difference in a horizontally flowing pipe depends on multiple factors, such as the fluid density, velocity, length of the pipe, and any obstructions or changes in elevation. However, the question only provides the fluid's density (1370 kg/m^3). To calculate the pressure difference accurately, additional information is required.

The pressure difference in a fluid flow system is determined by various factors outlined in Bernoulli's equation and the continuity equation. These equations involve parameters like fluid velocity, pipe diameter, and changes in elevation or potential energy. Therefore, without details about these variables or the pipe's characteristics (diameter, length, velocity), it's impossible to compute the pressure difference accurately.

Moreover, the pressure in a horizontal pipe may change due to factors like friction losses, which relate to the pipe's material and surface roughness, among other things. Viscosity, although not directly mentioned in the question, also affects pressure drop by influencing friction losses within the pipe. Hence, stating a definitive pressure difference without considering these variables is not possible, and thus, the correct answer is "Not enough information provided."

The correct answer is c) Not enough information provided.
