Manometer Reports Samples For Students

Introduction

The experiment was conducted to examine the validity of Bernoulli’s Principle as applied to the flow of water in a tapering circular duct. It employed the use of Bernoulli’s Theorem Demonstration Apparatus, hydraulics bench and a stopwatch to gather relevant data. The volume of water was measured and its flow was timed using the stopwatch. The two values were used to calculate the flow rate of the fluid. Additionally, the manometer readings were collected and used to compute the velocity of the fluid at each tapping position. The values were used to calculate the theoretical velocity head ...

Introduction

The null hypothesis for the experiment was that oxygen production is the same in both plants while the alternative hypothesis was that oxygen production and thus the rate of photosynthesis is higher in Ceratophyllum than in Cabomba due to its efficiency in carbon dioxide utilization (Kitaya, Murakami, & Takeuchi, 2003).

Materials and Methods

Experimental Design
The research question to be answered in the experiment was whether there is rate difference, in oxygen production, in oxygen production between Ceratophyllum and Cabomba. It was predicted that each of the plants would have different oxygen production rates. The dependent variable was the rate in oxygen ...

The Rate of Photosynthesis in Two Submerged Organisms (Cabomba and Ceratophyllum)

Introduction
In this experiment, the set alternative hypothesis was that the rate of oxygen production in Cabomba was significantly different from the rate of oxygen production in Ceratophyllum. This was informed by the report from a previous study by Van and colleagues (1976) that indicated that Cabomba had a lower rate of photosynthesis compared to Ceratophyllum and Hydrilla that had similar photosynthetic rate.

Materials and Methods

Experimental Design
The experimental independent variables were 6 grams for Ceratophyllum and Cabomba organisms while oxygen produced was the dependent variable. Water collected from the pond was used as the control in the experiment. The question ...
