Two possible overhead valve combustion chambers are being considered, the first has two valves and the second design has four valves per cylinder. The diameter of the inlet valve is 23 mm for the first design and 18.5 mm for the second design. If the second design is adopted, show that the total valve perimeter is increased by 60.8 per cent. If the valve lift is restricted to the same fraction of valve diameter, calculate the increase in flow area. What are the additional benefits in using four valves per cylinder?

Two cylinders of oxygen are connected to each other by a valve. The first tank is 50 liters in volume and contains oxygen at 27 °C and a pressure of 140.37 kPa, and the corresponding values for the other tank are 30 liters, 89 °C and 62.73 kPa. If the valve connecting the tanks is opened and the tanks are allowed to reach some equilibrium condition with the temperature being 50 °C. Answer the following: (a) the equilibrium pressure, (b)...

An activity based costing system is being considered at Evelia, nv to assign products overhead costs; these overhead costs are currently assigned strictly by number of units produced. First, the two overhead costs of Rent expense and Insurance expense would be allocated to three activity cost pools - Finishing, Sanding, and Other - based on resource consumption. The information used to perform these allocations is below: Overhead Costs: Rent expense: $2,000,000 Insurance expense: $1,650,000 Distribution of Resource Consumption across Activity...

The human heart has four chambers (two atria and two ventricles). In the human foetus, there is an opening between the right and left atria, and they function as one atrium. This opening closes after the birth. In some cases, it does not close completely. In most of these cases, this incomplete closure remains undetected throughout life. If a large opening occurs between the right and left ventricles, as seen in normal reptiles, children with this condition cannot survive without...

Two currently owned machines are being considered for the production of a part. The capital investment associated with the machines is about the same and can be ignored. The important differences between the machines are their production capacities (production rate × available production hours) and their reject rates (percentage of parts produced that cannot be sold). Consider the following table: Machine A Machine B Production rate 100 parts/hour 130 parts/hour Hours available for production 7 hours/day 6 hours/day Percent parts...
